Dear member of RadTech Europe,

I welcome you to another edition of our electronic magazine and would like to give you a short overview of all the things that have been happening over the last couple of months. Since the beginning of this year, work has continued apace with the filling of website content, and all articles from the past conferences should be available in the coming weeks. Once that has been realized, we will create videos explaining the full functionality of the website, helping you to utilize it to its full potential. Please remember to fill in your company profile on the website soon, as visits to the website are likely to increase exponentially.

We are also in the progress of expanding our membership loyalty program. This has started with the providing of RadTech membership certificates on a yearly basis, but will evolve to include other benefits.

As has been mentioned at the General Assembly held at our Conference in Basel last year, RadTech Europe is looking to actively reach out to end-users and other partners. One way in which we’ve done this is by having a stand at PaintExpo. With the help of the Metal Coating working group, we’ve been able to collect a number of impressive samples of metal coating applications and have the stand manned by people from the industry for the entire event. Feedback has been good, and we are looking forward to EuroCoat in Barcelona, where we will have our next booth. We have also worked to tighten our connection with RadTech North America, attending their highly successful Conference in Chicago and participating in the international luncheon with the other RadTech associations across the globe. Collaboration on a number of HSE topics is currently ongoing, and we are very happy that the international network is strengthening.

In the upcoming months, there will be a number of RadTech Europe events, with our first EB-specific event scheduled for 25 October in The

Netherlands. The EB project group has been very active in getting a good program together, coupled with a site tour of an end-user. This will take place back-to-back with our General Assembly, which will once again be offered online as well. In November we will be continuing our line of food safety seminars, with an event in Germany. More information will become available closer to the date, but you can be guaranteed of another excellent program!

As always, let me end with a thank you to all our active members, who through their input and hard work in the Committees and Working Groups help the Association and the UV and EB industry in general move forward. RadTech Europe is possible because of you.

If you have any ideas or suggestions, or wish to participate in one of our Working Groups or Committees, please do not hesitate to contact me or the Secretariat.

Yours sincerely,

David HelsbyPresident of RadTech Europe

RTE General Assembly 2012On the 24th of October, RadTech Europe will organize its annual General Assembly in The Netherlands, followed by a seminar on Electron Beam technology on the 25th, offering you the opportunity to easily combine both events. In addition, on the evening of the 24th a networking dinner will take place, to allow for informal discussions between members and participants at the seminar.

At the General Assembly, you will be informed of the most important activities of RadTech Europe over the last year and the plans for the future. This is also the ideal opportunity to share your views and suggestions with the Management Committee on the direction of the association, and to ask any questions.

In order to further increase participation, members unable to attend will once again be offered the possibility to participate and vote through an online webcast.

All members are kindly invited to participate at the General Assembly, with a formal invitation including more details to be issued shortly.

Subsidies for UV and EB in the NetherlandsThe Dutch government appreciates UV and Electron Beam Curing technologies as being environmentally friendly. Therefore companies in the Netherlands that invest in these technologies can apply for tax benefits over a scheme called MIA/VAMIL.

Starting in 2012, EB-technology and coating stations for EB-technology can make use of a random depreciation scheme for 75% of the investment and a 36% investment tax reduction. These benefits apply for the investment in the equipment and a part of the preparation of the installation of the equipment. UV-technology was already covered in this program.

For more information, please contact our EB working group through RadTech Europe’s Secretariat ([email protected]).

Make sure to attend the first RTE EB seminar on 25th October 2012

The General Assembly will be followed the next day by RadTech Europe’s first dedicated EB seminar, to be held at Svedex in Varsseveld (NL). The seminar, which is to be held in German, will focus on the advantages and possibilities of EB technology, and a number of real-life examples of the practical implementation of the technology into production processes. The event will start with presentations outlining the fundamentals

of EB, requirements for EB installations, information on the raw materials and chemistry, followed by a number of case studies. After lunch, there will be a tour around Svedex, allowing attendees to visit an operational EB installation.

The full program and further details will become available in the coming weeks, but please mark your calendar already to attend these exciting events!

RadTech Europe at other eventsRadTech Europe showcases UV and EB metal applications at PaintExpo 2012

As announced at our conference last year, one of our primary areas of attention this year has been to increase RadTech Europe’s active outreach to end-users. Aside from our own seminars and our website and excellent information database, we are now actively engaging end-users by promoting UV and EB technology at their events.

After the successful metal coating seminar in Zelzate last year, our metal coating working group decided on a different approach for 2012. With a number of interesting and attractive examples of UV and EB metal applications available, the next step was to get the message out to the end-users. With help from the entire group, a booth was organized at the PaintExpo in Karlsruhe, the international trade fair for industrial coating technology, which was held from the 17th till the 20th of April.

The 4th PaintExpo had 8,028 visitors from a total of 63 countries from all continents. A number of eye-catching samples and posters explaining the advantages of UV and EB technology generated a good amount of traffic and a number of serious inquiries. It was especially encouraging to see that a significant number of these were from companies who had not been involved in energy curing before, and were considering a move from traditional coatings. With members of the metal coating group on hand all four days to answer any questions, the booth certainly proved an encouraging first step into a new direction for the association.

RadTech Europe at EuroCoat 2012As a follow-up to the PaintExpo presence, RadTech Europe will also have a booth at the upcoming EuroCoat, to be held in Barcelona from 2 to 4 October 2012. As with PaintExpo, the goal will be to bring end-users in contact with the

advantages of UV and EB technology for metal applications. With a strong set of case studies, a good number of attractive and illustrative samples and a dedicated group to man the booth, we are looking forward to making this a success.

RTE website knowledge center completedThe completely renewed RadTech Europe website offers a clear, fresh and very thorough portal for anyone with an interest in UV and EB curing. The stand-out feature, the vast and fully searchable knowledge center, which contains proceedings of previous Conferences and events, and other articles, has now been completely filled! These documents are available free of charge for members upon log-in, whilst non-members can purchase these. Make sure to visit the website from time to time as new articles will be uploaded frequently. The Knowledge Center also contains the bookstore and more information on regulatory affairs (legislation, HSE and public affairs).Another big addition is the member search, where all company details of our members will be shown (similar to the former member directory on the old website). This feature will not only show contact details, but will also contain a search engine where members can be found under their main category and products, members have the possibility to adjust their data themselves and the posted news items will be linked to their profile automatically. This means more exposure for our members on the RTE website! All members received their personal username and password a few months ago. With this account, they have access to the members only area of the website (where articles can be downloaded free of charge) and they can edit their company profile.

New advertising possibilitiesMember companies can not only benefit from more exposure by sending in their press releases to the RTE Secretariat, they can also showcase their own work by contributing special UV and EB business cases. This new feature will give RTE members a whole new way of effectively communicating with their target group. Instead of placing a banner with only limited space to advertise, RadTech Europe offers its members the opportunity to advertise more detailed on (e.g.) new

products, innovations and other relevant topics for the UV/EB industry. Members whom are interested in this exposure may contact the RTE Secretariat or have a look at the Advertisement & Media Rates 2012 brochure which can be found on the RTE website as well.

Drupa report 2012314,500 experts from more than 130 countries came to Drupa in Düsseldorf, 75,500 less than in 2008, in line with the general developments in the printing industry worldwide. However, the general figures from the trade floor showed that the visitors present were, more than in previous editions, from the higher echelons of company management, with specific investment intentions.

The dominating themes at Drupa 2012 were automation, packaging printing, digital printing, hybrid technologies, web-to-print applications and environmentally sound printing. Also attracting great attention was the future theme printed electronics which was highlighted at Drupa in a variety of fields: at the Drupa innovation park, Drupa cube, in a Highlight Tour and at many stands of Drupa exhibitors.UV and EB had a significant presence at the event, with the demonstration of the COMEXI OFFSET CI8 in particular generating a lot of interest. This product line is based on 6 offset printing units and 2 flexo printing units around a central impression drum (CI) with EB (electron beam) offset inks and Flexo EB for coatings and backgrounds. Also noteworthy was that a total of 30 Vendors displayed UV LED curing equipment at Drupa 2012.

For the final impression from the Drupa organization, see: http://www.youtube.com/watch?v=ND2c0SpOtdo&feature=player_embedded

The next Drupa will be held from 2 to 15 June 2016.

News from RadTech North AmericaIn this section relevant news from RTNA is posted.

Looking Back on a Successful RadTech 2012From April 30th til May 2nd, the Hyatt Regency in Chicago was the site for RadTech North America’s bi-annual UV & EB Technology Expo and Conference, the place to be for the latest information from the UV, EB and UV LED industry with 24 Technical Conference tracks and eight end-user sessions.

According to RadTech North America, turnout was excellent, with record attendance figures for end users for the Technical Conference. . The show floor, which played host to 77 exhibitors, also saw a good amount of traffic.

A three hour UV LED End Users Session generated a lot of attention with a session that covered the basics of LED technology, coatings and ink jet applications, and photoinitiator and resin selection as well as UV measurement. The session concluded with a 45 minute panel discussion featuring six diverse industry experts. The session on packaging and printing applications was also very well-attended, with presentations from Nestlé and the Print Industries Association of America, among others.

As in 2010, an international RadTech luncheon took place on the first day of the event, providing the opportunity for the various RadTech associations across the globe to meet and strengthen the ties. Possible initiatives, such as the possibility of a global HSE information portal were discussed and will be further explored in the coming months.

This year, the Emerging Technology Awards for innovations in (applications of) UV en EB technology were handed to UniPixel Inc, The Woodlands, TX, for conductive film that is manufactured using a low-cost, UV-curable, transparent roll-to-roll process by micro and nano-embossing. Interprint NA, Pittsfield, MA, for EB coatings for decorative laminates on film substrates and HRL Laboratories LLC, Malibu, CA, or UV used to make the world’s lightest structure.

Light Work withUV-LED Sources

A Pera Technology company

I have enjoyed the past few months gaining hands-on experience with curing using UV light emitting diodes (UV-LED). Hitherto my practical knowledge has been limited to using a small laboratory spot-led source and to observing a few commercial installations, mostly involving jet printing. Now I have ready access to three distinct diode arrays, mounted on an industrial conveyor system.

Of necessity there are constraints to playing with the novel systems; the equipment is a contribution from a partner in an EU-FP7 project and the experimental programme has to conform to the project’s work plan. Nevertheless it is exciting, late in my career, to be involved in formulation and curing in a frontier region of radcure technology.

Experience and theory provides a guideline for planning experiments and the relevant literature is growing apace, but the exercise has served to reinforce my view that radcure R & D is still an essentially practical subject. There have been some surprises and clearly there is much to learn. For those as yet not familiar with UV-LEDs, recent conference and trade literature contains several articles offering comparisons with using mercury lamps.

UV-LED sources have progressed rapidly in a comparatively short time. Sources emitting at more wavelengths are becoming available. The power output that the devices can deliver at each of the various emission peaks is increasing. As the emitted radiation is confined to a narrow band width, the intensity at the peak centre can be very high. Nonetheless the total power

densities in the UV region remain well below those of a typical mercury lamp. This is especially so for those UV-LEDs that emit in the ‘shorter’ wavelength region, around 360 nm.

On first consideration, the limited spectral range and irradiative intensity could be compensated for by accepting slower throughput or by adding more UV-LED arrays but this raises issues of cost, productivity and hence commercial viability.

For UV-LEDs the single peak emissions, the comparatively low intensities and the restriction of available sources to near visible wavelengths have implications for the cure profile and add new dimensions to the formulator’s task of selecting the types and concentrations of photoinitiator for any particular product.

The question of UV-LED heat effects is particularly interesting. A typical mercury lamp emits ca. 55% of its energy as infrared radiation. This influences cure by, for example, maintaining the coating temperature above the growing polymer’s Tg for a longer period as the curing proceeds. Although the UV-LEDs need cooling in order to remove heat generated by the diode itself, the near monochromatic emission lacks an infrared component. Nonetheless the absorbed energy from the UV radiation downgrades to heat and significant warming may occur with relatively short dwell times. For the present I confess to lacking sufficient experience to be able to give an opinion on the heat-effect on the quality of cure when using UV-LEDs. Gaining such information is the stimulating part of research!

NewsroundChemical majorsCytec to spin off Coating Resins

Cytec has retained JP Morgan Chase to consider a potential divestment of its coating resins business. Chief executive Shane Fleming, who made the announcement at the same time as presenting the company’s end of year results, said the bank would also analyse other options, but a divestment was the most likely outcome. Any option would result in a 100% separation of the business from the rest of Cytec, he said.

A firm decision is expected in the second quarter of this year. “This will give us time to understand the financials and organisational structure of the separated business. We hope to announce a transaction in the fourth quarter,” he added.

A separation would include Cytec’s pressure sensitive adhesives product line, which shares technology and manufacturing with Coating Resins.

Sales from the coating resins segment account for approximately half of Cytec’s total sales. However, operating earnings as a percentage of sales are poor compared to Cytec’s other business segments. Operating earnings last year at the coating resins segment declined slightly compared to the previous year to $65 million or 4% of sales of $1.54 billion. The return from the prior year was not much better. In 2010, operating earnings of $68 million were 5% of sales of $1.42 billion.

Cytec’s three other reporting business segments show a much better rate of return. Engineered Materials, responsible for 29.5% of sales in 2011, saw operating earnings as a percentage of sales of 15%. The In Process Separation business, responsible for 11% of sales, returned operating earnings of 21% of sales; and the Additive Technologies segment, responsible for 9% of sales, saw an earnings return on sales of 13%.

Last year, volume sales of coating resins declined. The business, which has markets in North America, Asia Pacific, Latin America and Europe – the largest being Europe with nearly twice as many sales as in North America – saw volumes drop 11% year-on-year in the 2012 fourth quarter due to weakening demand across global industrial markets, particularly in Europe and Asia

Pacific. For the full year, volumes were down 6%. Fleming said there was very limited visibility through the end of the year and the segment operated with short lead times and erratic order patterns.

The segment achieved 8% higher selling prices in the fourth quarter despite the weak demand environment, which more than offset higher raw material costs.

Cytec Industries as a whole increased net earnings by nearly 21% last year to $207.8 million on sales of $3.07 billion, 12% higher than the previous year.Cytec Industries, 31 January 2012

Total acquisitions boosts income at Arkema

Arkema has upgraded its long-term performance targets after posting net income growth from continuing operations in 2011. The French speciality chemicals company now hopes to reach a sales target of €8 billion and EBITDA-earnings of €1.25 billion by 2016 via a combination of organic growth including several projects underway and bolt-on acquisitions.

Annual income from continuing operations rose 33.6% last year to $572 million despite income dropping in the fourth quarter due to significant year-end destocking by customers in the refrigeration and coatings industries. Fourth quarter income from continuing operations fell 17% to €76 million from €92 million in the fourth quarter of 2010, which was characterised by unusual restocking by customers.

Sales rose 17% in the fourth quarter and 21% in the year to €5.9 billion. Some 9% of this reflects the integration of speciality resins bought from Total on 1 July, which achieved €408 million in sales in the second half of the year.

The acquisition of the alkoxylates business from Seppic, which closed on 31 December last year, expands the speciality products range of Arkema’s subsidiary Ceca and supports the growth of new rheology additives ranges of Coatex. Sales of this business amounted to €53 million in 2011. The acquisition of Chinese companies Hipro Polymers and Casda Biomaterials, which closed on 1 February this year, complements Arkema’s bio-sourced speciality polyamide range, strengthens its presence in Asia and increases its position in green chemistry.

Combined sales for these two companies were around $230 million in 2011.

The sell off of Arkema’s vinyls activities to Klesch Group is at a consultation stage with workers councils and is awaiting approval from relevant antitrust authorities. The deal is expected to close by the middle of this year. The business made an EBITDA loss of €24 million in 2011 amid a challenging European construction market and significant customer destocking at the end of the year. Profitability was also impacted by strike action at the LyondellBasell refinery in Berre, France, in the last quarter. Deduction of non-recurring expenses of €505 million related to vinyls activities and results of operations classified as discontinued brought year-end net income down to negative €19 million.Arkema, 8 March 2012

Successful 2011 and positive outlook for 2012 for BASF

Growing demand from the global automotive industry is expected to drive sales at BASF Coatings in 2012, just as it did in 2011. The company is also expecting to see significant earnings improvement at the segment this year, as there won’t be the same level of high special charges.

Coatings sales and volume increased last year thanks mainly to a favourable global automotive market, but also year-on-year growth in other areas including decorative paints in South America and strong demand for coil coatings from the Russian steel industry. Sales rose by €223 million or 8.7% to €2.88 billion in 2011, while volume rose by 6% and prices increased by 4%. However, income from operations was lower than in 2010 owing to special charges associated with the sale of the Relius brand of decorative paints - the sale affected production sites in Memmingen, Germany, and Deurne, the Netherlands.

Increased demand for automotive coatings came from customers in both Europe and Asia, but especially China. Automotive refinish coatings also saw a rise in sales, with new customers attracted and price increases, even as the business environment remained “competitive”.

Sales volumes for coatings for wind turbines also grew.

A sharp increase in raw material costs could not be fully passed on to the market. A strategic plan is to strengthen its coatings presence in growth markets in Asia and Eastern Europe – particularly in China, India and Russia.

businesses in BASF’s Functional Solutions segment – the other two being catalysts and construction chemicals. Functional Solutions represents 15% of total sales. As a segment, income from operations was €30 million below the level of the previous year at €427 million, mainly as a result of the higher special charges at the coatings division. Segment sales rose 17% in the year to €11.36 billion as volumes increased 9% and prices rose 10%.BASF, 24 February 2012

A strong year for DSMDSM’s Performance Materials cluster,

which includes DSM Resins, Dyneema fibres and DSM Engineering Plastics, failed to make a profit before taxes and interest in the fourth quarter as volumes plummeted by 15% compared to the same period a year ago.

The materials sciences businesses of DSM were hit hardest when economic growth in Western Europe stalled in the fourth quarter of 2011 and customers adjusted their year-end inventories downwards. The businesses also felt the impact of credit tightening in China as the government there implemented measures to control inflation.

DSM said weak markets in building & construction, Electrical & Electronics and European automotive lowered demand in both DSM Engineering Plastics and DSM Resins, while DSM Dyneema suffered from lower volumes in the vehicle protection business. Higher pricing did not compensate for lower volumes and fourth quarter sales at the cluster declined 2% to €627 million.

For the full-year, earnings before interest and taxes at the cluster were flat at €162 million compared to €163 million in 2010, while annual sales rose nearly 10% helped by higher pricing.

Special charges of €18 million from restructuring at DSM Resins were made at group level in the fourth quarter. During 2011 the business unit merged its technologies into one coating resins business unit and announced the closures of a number of its smaller factories. The company plans to make savings of €20-30 million a year in 2013. Separately, the closing of a Swiss tape manufacturing facility in Flaach, affecting approximately 25 Dyneema employees, also resulted in impairment charges.DSM, 29 February 2012

Coatings CompaniesDIC buys New Zealand’s Pacific Inks

DIC Corp, the Japanese printing inks manufacturer, is to acquire Pacific Inks of New Zealand, giving DIC access to Pacific’s water-based flexo inks and a stronger position in Asia-Pacific.

The deal is expected to add JPY2.5 billion (about $32.4M/€25.3M) to DIC’s annual sales by fiscal 2015 and will involve some rationalisation of newly acquired facilities and plants, although no details were given.

According to DIC, demand for packaging inks remains firm in developed countries and is forecast to grow by around 10% annually in Asia-Pacific for the foreseeable future. At the same time, environmental awareness is increasing rapidly in Asia-Pacific. DIC also gains Pacific’s proprietary Accubatch automatic ink dispensing and blending system. The system allows customers to blend their own inks on site.

DIC has said strengthening its packaging inks business is a strategic theme for the company.

Pacific’s principle plant is located in Auckland, New Zealand. It also has plants in Sydney, Melbourne and Adelaide in Australia; in Singapore, Malaysia and China; and in the UK. Its product line is concentrated on packaging inks for cardboard.

Net sales at DIC Corp. for the six months ended 30 September 2011, were down 3.6% below the year ago six months period at JPY378.9 billion (about $4.9BN/€3.8BN). Operating income over the same period was down 13.8% at JPY17.9 billion, but net income was up 2.4% at JPY12.5 billion. DIC Corporation, 27 December 2011

AkzoNobel buys remaining Metlac shares and strengthens packaging coatings

AkzoNobel is to acquire the remaining shares in Italian packaging coatings producer, Metlac Group. The acquisition is subject to antitrust approval, but it is expected that it will be finalised in the second quarter of this year. Financial details were not disclosed.

AkzoNobel inherited Metlac shares from its acquisition of ICI in 2008. The Dutch paint and speciality chemicals producer says the deal underlines the company’s strong commitment to supporting the coatings and inks market for metal packaging by securing the future of a well-recognised supplier.

“This acquisition will reinforce our

DIC Corp. Q1-3DIC Corp, the Japanese printing inks,

graphics arts materials and chemicals company, reported a nearly 16% year-on-year fall in operating income for the nine months to the end of 2011, blaming persistently “harsh operating conditions”.

The company said the market began to reverse in the second quarter owing to a global economic slowdown provoked by the European sovereign debt crisis combined with flagging economic growth in Asia. These factors caused demand in Japan and overseas to “dwindle”. Falling shipments of printing inks and products for the electrical and electronics industries in Japan and overseas countered the positive impact of a substantial increase in shipments of thin film transistor liquid crystals (TFT LCs) used in LCD televisions.

Nine month operating income fell to JPY27billion (€263.3m/$349.9m) on 4.5% lower sales year-on-year of JPY561.4 billion. Net income for the period decreased 4.5% to JPY15.9 billion, partly reflecting a gain from sales of subsidiaries’ stock.

In Japan, sales of printing inks and supplies declined more than 6% compared to the equivalent nine month period in the prior year to JPY69.9 billion, while operating income declined over 7% to JPY2.7 billion. Despite benefiting from special procurement demand for flexible packaging applications, notably beverage containers and food packaging, in the wake of the March 2011 earthquake in the north-east of the country, sales of gravure inks remained on a par with the nine months to the end of December 2010, reflecting difficulties in procuring certain raw materials because of the earthquake. Sales of offset inks and news inks declined as an existing downward trend was exacerbated following the earthquake by paper shortages and raw material procurement problems.

Outside of Japan, in the Americas and Europe, year-on-year sales of inks and supplies fell by nearly 11% in the nine months to JPY172.5 billion. The lower sales, coupled with higher raw materials prices, caused operating income from these geographies to plunge almost 46% to JPY2.8 billion. Sales fell in both North America and Europe, despite a slight increase in sales of packaging inks,

Raw materialsNew photoinitiating systems designed for polymer/inorganic hybrid nanocoatings

There have been significant advances in the use of nanomaterials in coatings in recent years. UV cured inorganic-polymer nanocomposites exhibit significantly improved film properties (compared to the control polymer systems), such as hardness, flexibility, scratch and chemical resistance, and the coatings are finding use in abrasion-resistant coatings, protective coatings, glass coatings and novel optical devices. One of the critical issues with these coatings is to ensure good dispersion of the nano-inorganic component, since the particles tend to agglomerate due to their high surface energy. This article (which reads a little like a review with its 82 references) reports novel synthetic methodologies using photoinitiating systems for the in situ preparation of epoxy and (meth)acrylate-based nanocoatings containing clay or metal nanoparticles.

The article comprises a number of sub-sections on various methodologies: clay/polymer nanocomposites by photochemical processes via direct photoinitiation (using photoinitiators based on ionic compounds that may intercalated between the clay nanolayers); intercalation of photopolymerisable monomer by ‘click chemistry’; photoinduced-activated monomer polymerisation (and particularly the application cationic polymerisation); metal/polymer nanocomposites by photochemical processes (using a redox process to introduce silver and gold nanoparticles); photoinduced nano-grafting from self-assembled monolayers

on gold; and metal oxide/polymer hybrid nanocomposites by photochemical processes (using sol-gel technology).Y Yagci, Journal of Coatings Technology and Research 2012, 9(2), 125-134

Enhanced thermal and surface properties of waterborne UV-curable polycarbonate-based polyurethane (meth)acrylate dispersion by incorporation of polydimethylsiloxane

The increasing sophistication in design of waterborne PUs has enabled the performance gap with their solventborne counterparts to be narrowed. The present article represents one of the approaches that may be adopted combining siloxane modification of the PU with UV curing capability. Initially a polycarbonate diol was reacted with isophorone diisocyanate to produce a NCO-terminated intermediate. Hydroxyl-terminated polydimethylsiloxane was then incorporated by reaction with the NCO groups, followed by incorporation of dimethylol propionic acid to produce ionisable groups. Finally the prepolymer was end-capped with either HEMA or pentaerythritol triacrylate (PETA), neutralised with an amine, dispersed in water with a photoinitiator being added. The UV-curing behaviour of coatings was monitored by FTIR and photo-DSC (DSC equipped with a photocalorimetric accessory).

The presence of the siloxane groups in poly(urethane-carbonate) dispersions was shown to markedly reduce surface free energy of coatings (contact angle measurements) and increase the temperature of onset of thermal degradation (TGA). The UV curing rate and final conversion was seen to be solely dependent on functionality of the acrylic component (HEMA or PETA). The Tg and mechanical properties of coatings could be regulated by varying the siloxane content or the functionality of the acrylic component. Accordingly it is demonstrated how the properties of low surface energy PU coatings may be manipulated by respectively varying these two components.H-D Hwang, H-J Kim.

Living cationic polymerization of a coumarin-substituted vinyl ether and reversible photoinduced crosslinking of the resulting homopolymers and amphiphilic block copolymers

Materials, such as poly(vinyl cinnamate)s, have been widely used as negative photoresists in the printing and electronics industries. Surfaces coated with poly(vinyl cinnamate)s become insoluble after exposure to UV light. Coumarin derivatives undergo dimerisation under UV irradiation with λ>300nm; however, unlike cinnamates, they also undergo a cyclobutane photocleavage reaction when irradiated with UV light of λ≤300nm. This paper describes the synthesis of novel coumarin-containing vinyl ether monomer and its living cationic polymerisation by investigating various initiating systems.

4-Methyl-7-(2-vinyloxyethoxy)coumarin was prepared by reacting 7-hydroxy-4-methylcoumarin with 2-chloroethylvinyl ether in the presence of various bases (best yield was obtained using sodium hydride).

Living cationic polymerisation was carried out using tin tetrachloride in the presence of tetra(n-butyl)ammonium bromide at 0°C. It was demonstrated that amphiphilic block copolymers could be prepared.

The coumarinyl moieties were crosslinked by UV irradiation (λ=366nm), and the crosslinked sites were shown to be cleaved by UV light of λ=254nm. The crosslinking behaviour was studied using UV and FTIR spectroscopy.J Motoyanagi, I Nishimura, M Minoda, Journal of Polymer Science, Pt A Polymer Chemistry 2011, 49(21), 4701-4707

FormulationsCationic UV curing behavior and thermal properties of oxetane-modified polysiloxane prepared from tetraethyl orthosilicate

The two organoalkoxysilanes, 3-glycidyloxypropyl trimethoxysilane (GPTMS) and 2-(3,4-epoxycyclohexylethyl)ethyl trimethoxysilane (TRIMO) have been used for preparing cationic UV curable polysiloxanes, but both the hydrolysis and condensation of the alkoxysilane moiety are very slow in the absence of a catalyst. The use of a basic catalyst, such as an amine, would probably neutralise the Lewis acid produced by the cationic photoinitiator and inhibit cure. An acid catalyst would ring open the epoxy groups and cause gelation during synthesis or storage. Most of the literature has concentrated on epoxy-based formulations, whereas this paper focuses on oxetane-based formulations.

A mixture of tetraethyl orthosilicate (TEOS) and acidified water was heated at room temperature for one hour, 80°C for 10 hours

and 150°C for 3 hours. Nitrogen was flushed through to remove the ethanol. The temperature was reduced to 120°C and 3-ethyl-3-hydroxymethyl oxetane (EHO) and titanium tetraisopropoxide was added, and the reaction stirred until all ethanol peaks in the 1H NMR spectra disappeared completely.

Four formulations comprising the EHO-polysiloxane, EHO and 3,3 -́[oxydi(methylene)bis(3-ethyloxetane)]

(DOX) were prepared and cured with 2% triphenylsulphonium salt. PhotoDSC revealed that the maximum photopolymerisation rate and final oxetane conversion decreased with increasing EHO-polysiloxane content, due to a sharp increase in formulation viscosity. Both DMTA and DSC results showed that the thermal stability was improved due to the compatibility between EHO-polysiloxane and the diluent mixture, which resulted in greatly increased crosslink density and enhanced pencil hardness.F Zhan, X Cheng, W Shi, Journal of Applied Polymer Science 2012, 123(2), 717-724

UV curable glycidyl carbamate based resins

Over the last 10 years, Dean Webster and his group have undertaken studies evaluating the curing potential of glycidyl carbamates (GC) by various mechanisms (in particular reaction with amines). Apparently although endcapping epoxy groups with acrylic acid to form acrylates is well-known, this has not been done for glycidyl carbamate resins, and therefore this omission is now rectified. In this preliminary study, biuret glycidyl carbamate, isocyanurate glycidyl carbamate and an alcohol-modified isocyanurate glycidyl carbamate were prepared and then reacted with acrylic acid to form a series of acrylated GC resins. Formulations comprising these acrylated GC resins, reactive diluents (including 2-(ethoxyethoxy)ethyl acrylate, 1,6-hexanediol diacrylate and ethoxylated TMPTA), a photoinitiator (Irgacure 184) and an amine co-initiator, were prepared and their curing kinetics (using realtime FTIR spectroscopy) and film properties (including pendulum hardness, impact strength, adhesion, flexibility and MEK double rubs) were evaluated. Thermal properties were also studied using DSC, DMA and TGA techniques.

Modification of the GC resin with an alcohol (in particular ethylene glycol propyl ether) to form ultimately an alcohol-modified isocyanurate glycidyl diacrylate reduced the viscosity of the oligomer. The degree of conversion increased with the extent of alcohol modification. UV cured GC coatings gave good all-round performance, with flexibility increasing with extent of alcohol modification.U D Harkal, A J Muehlberg, D C Webster, Progress in Organic Coatings 2011, 73(1), 19-25

UV-curable waterborne polyurethane-acrylate: Preparation, characterization and properties

Waterborne polyurethane acrylate dispersions are an attractive coating technology, providing environmental benefits, ease of application and a high level performance properties (with wide formulation options). In this work a UV curable polyurethane acrylate oligomer was prepared from isophorone diisocyanate, polyether polyol, dimethylol propionic acid and hydroxyethyl methacrylate. The prepolymer was dispersed in water using triethylamine to neutralise the carboxylic acid groups (but the PU was not chain extended).

ProcessesKinetic study of photoinduced quasi-simultaneous interpenetrating polymer networks

Interpenetrating polymer networks (IPNs) have been prepared by a number of researchers by UV irradiating a mixture of (meth)acrylates and epoxides as a means of gaining the benefits of both systems. It is known that the acrylate monomer polymerises faster than the epoxide system, but that there is a decrease in oxygen sensitivity for the acrylate monomer due to increasing viscosity of the mixture. The sensitivity of the cationic polymerisation to temperature has also been explored. There have also been some reports about the photoinitiator systems that can be used.

This paper describes the kinetics of formation of IPNs based on a cycloaliphatic epoxide (3,4-epoxycyclohexylmethyl-3 ,́4 -́epoxycyclohexyl-carboxylate) and a methacrylate (an ethoxylated bisphenol A dimethacrylate) in a 1:1 weight ratio, using real-time FTIR spectroscopy and real-time ultrasound reflectometry/near infrared spectroscopy respectively to measure the real-time conversion of the monomers and to monitor the conversion and the complex dynamic shear modulus in situ and simultaneously. The effect of reaction kinetics on IPN morphology, phase separation and final composition was assessed for different experimental conditions.

It was found that the rate of IPN formation was affected by the photoinitiator concentration and the lamp system. Different kinetics were observed for the hybrid mixture when two different lamp systems (a polychromatic UV-vis Hg-Xe light source and a monochromatic 366 nm light source) were used, which in turn might affect the polymer morphology and final properties.

The best properties were obtained using the polychromatic light source. It was also shown that the shear modulus of the hybrid system increased for some time after the lamp was switched off, relating to the living character of the cationic polymerisation.M de Brito, X Allonas, C Croutxé-Barghorn, M Palmieri, C Dietlin, S Agarwal, D Lellinger, I Alig, Progress in Organic Coatings 2012, 73(2-3), 186-193

Photoinitiated cationic polymerization of vinyl ethers using substituted vinyl halides in the presence of metallic zinc

There is tremendous interest in the preparation of tailor-made macromolecular structures for a wide variety of application areas. Common radical polymerisation techniques have a number of drawbacks, some of which can be overcome by using living cationic polymerisation. Among the living cationic polymerisation techniques, the Lewis acid-catalysed method can be light-induced: a photochemically generated cationic species (either a carbocation or Brønsted acid) from photoinitiators containing a halogen react with a monomer (eg vinyl ether) to form a halide-monomer adduct. Addition of new monomers to the adduct is catalysed by Lewis acid (eg metal halides). However, metal halides are either deactivated or transformed to weaker Lewis acids by the presence of atmospheric moisture.

One method of overcoming this is to use the more water-tolerant Lewis acids eg ytterbium triflate. Alternatively zinc can be added as a reducing agent for free radicals, allowing the in situ formation of the Lewis acid zinc halides. So photolysis of vinyl halides affords vinyl cations for the initiation step and concomitant formation of zinc halides for the propagation step. This brief communication reports the cationic living polymerisation of isobutyl vinyl ether, initiated by the photolysis of a substituted vinyl halide, 1-bromo-1,2,2-tris(p-methoxyphenyl)ethane (AAAVB), in the presence of metallic zinc in solvent. A ten-fold excess of metallic zinc was used because it has limited solubility in organic media.

The use of metallic zinc allowed more control of these assisted polymerisations. The method was used to crosslink several difunctional monomers, and it was argued that AAAVB and metallic zinc had potential practical value for crosslinking vinyl ether-type monomers.

Access to nanostructured hydrogel networks through photocured body-centred cubic copolymer melts

Hydrogel networks are finding a lot of interest for various biomedical applications, such as encapsulation media, chemical and drug delivery systems and tissue scaffolds. The performance of these applications is dependent on control of various hydrogel characteristics (eg elasticity, modulus, mesh size) and equilibrium water content. Hydrogels are typically formed from random physically or chemically crosslinked networks of hydrophilic polymers: this inherent randomness creates heterogeneity in the formed networks and affects their properties. Block copolymers have the ability to phase separate at the nanoscale, and can be used to form tethered micelle networks. The strategy here is to use blends of sphere-forming AB diblock and ABA triblock copolymers that are melt processed and subsequently vitrified to preserve their nano-scale structure. Pre-structuring in the melt state takes advantage of the near-equilibrium conditions produced by annealing in the melt state, avoids any concentration effects associated with solution-based network formation and eliminates the potential trapping of organic solvent during the gelation process.

In this paper, AB diblock and ABA triblock copolymer blend-based hydrogels, including partially epoxidised polybutadiene-b-poly(ethylene oxide) block copolymers, were combined with thermally stable photocuring chemistry (low levels of 4-iodophenyldiphenylsulphonium triflate). The block copolymers were amenable to curing through cationic ring opening polymerisation of the epoxide groups. The ePB-PEO diblock, ePB-PEO-ePB triblock copolymers and photoinitiator were melt-processed into disks, annealed above the PEO melt transition (65°C) to facilitate assembly of the cubic spheres. They were then exposed to UV light at 100°C, transforming the targeted melt morphology to the cured solid. Swelling tests showed isotropic behaviour, with complete preservation of the pre-swollen shape. Simultaneous photopatterning during curing was demonstrated using a simple making, giving the possibility of more complex photopatterning applications.V F Scalfani, T S Bailey, Macromolecules 2011, 44(16), 6557-6567

Raw materialsD1479 stable liquid BAP photoinitiator and its use in radiation curable compositionsWO 2012 003106, June 2011, DSM IP Assets BV, USA

In the last twenty years, there has been much interest in the acylphosphine oxide photoinitiators, which have near visible absorption, but photobleach (or lose their yellow colour) on irradiation. However, the monoacylphosphine oxide, 2,4,6-trimethylbenzoyl diphenyl phosphine oxide can cause undesired crystallisation effects (leading to inclusions and a loss of clarity). Some bisacylphosphine oxides have poor solubility in common monomers and oligomers, which can limit the amount of photoinitiator that can be dissolved in a composition.

This patent describes a liquid photoinitiator composition comprising a bisacylphosphine with the following structure:

where Ar1, Ar2 and Ar3 are independently a substituted or unsubstituted aryl group.

Coating compositions for optical fibres, metal and concrete comprise at least one free-radical polymerisable component and a combination of at least two photoinitiators, ie bis(2,4,6-trimethylbenzoyl)phenylphosphine and

bis(2,4,6-trimethylbenzoyl)phenylphosphine oxide. The bis(acyl)phosphine is stabilised by at least one of the following techniques: low oxygen permeability packaging, refrigeration during shipping and storage, and inert gas blanketing.

A photoinitiator compositionWO 2011 030089, September 2010, Sun Chemical B.V., UK

Photoinitiator compositions for UV curable applications, particularly for LED (Light Emitting Diode) sources are described.

UV LED curing is of great interest because of the low temperature of operation and the extremely long life of LEDs when compared to the conventional medium pressure mercury arc (MPMA) lamps. However, in contrast to the polychromatic emission of the MPMA sources, when formulating inks for use with monochromatic LEDs, it is necessary to use photoinitiators that are tuned to the wavelength of the light source.

In addition, limitations due to health and safety labelling mean that it is difficult to achieve adequate levels of cure with UV LED light sources.

A unique photoinitiator blend is suggested that has been found to significantly increase cure speed compared with other initiator blends disclosed for use in UV LED curing.

A blend is described in an ink where the ink contains 2-15% by weight of an aminoalkyl acetophenone and a thioxanthone (in a 9.9:1 to 1:9.9 ratio) in conjunction with 1-10% of a multifunctional aminobenzoate synergist. Rapid cure speeds, up to 99 m/min, were seen with the photoinitiator blends described in coloured ink recipes.

FormulationsLED curing of radiation curing floor coatingsWO 2011 084554, December 2010, DSM IP Assets, B.V., USA

Radiation curable floor coatings offer many benefits over their VOC-containing counterparts. The UV cured coatings have no VOC components, are virtually instantly cured, allow immediate transport, are a one pot product and so offer no pot life issues or wastage. However, the use of UV lamps does create some environmental concerns from the mercury lamps and ozone generated as part of the lamp operation. LED lamps offer the potential to overcome these concerns, although current UV curable coatings are not suitable for efficient LED curing. Cure speeds would be too low for the process to be commercially viable and the final cured film would not have the required properties.

A composition is described as being capable of curing under LED irradiation with a wavelength of 100-900nm. The cured coating has a % Reacted Acrylate Unsaturation (%RAU) of 60% or greater.

The coating comprises radiation curing oligomers, reactive diluents and at least one photoinitiator. The use of Type I and II initiators and photosensitiser mixtures are described that give suitable %RAU values. The patent provides a list of Type I and Type II photoinitiators and photosensitisers with absorbance in the 100-300nm, 300-475nm and 475-900nm regions.

Photosensitive adhesive compositionEP 2319893, July 2009, Hitachi Chemical Co, Japan

Photosensitive adhesives often lack reliability where they are applied in patterns in the manufacture of semiconductor devices. Insufficient adhesive bonding can occur in the case of thermo compression. It has been found that the use of the lowest melt viscosity in a specific temperature range, after pattern formation, can give excellent thermo compression bonds at low temperatures and allow good connection of the semiconductor wafers.

The adhesives claimed in this patent comprise (A) an alkali-soluble resin, (B) a thermosetting resin, (C) a radiation-polymerisable compound, and (D) a photoinitiator, and (E) a thermal radical generating agent.

The radiation polymerisable compound (C) preferably contains a monofunctional (meth)acrylate resin. This allows pattern formability, but keeps the crosslink density low. Outgassing from the adhesive is reduced by ensuring that the weight loss is less than 5% at 150°C. The alkali-soluble resin is preferably a thermoplastic resin having a carboxyl and/or hydroxyl group (typically a polyimide).

The adhesive can be applied to a base material and heated to dry and cure the thermosetting resin. The adhesive coated sheets can be laminated to another material and UV cured. Adhesives of the described composition demonstrate good pattern formability and bonding under thermo compression.

ProcessesCoating agent for poly(methyl methacrylate) panel nano imprintingUS 2011 0130483, March 2010, Hyundai Motor Company, Korea

Automobile instrument clusters receive high levels of incoming light and can be a source of discomfort to the driver if light is reflected. To overcome this problem, a cluster cover can be provided to block this light, or the cluster can be deep inside the dashboard, or it can be curved. However, this limits the design freedom and so is not preferred.

Nano-imprinting techniques can be used to create repetitive patterns on a polymer film without the need for electron beam lithography and have been used in IT (Information Technology) industries for some time. Such nano-imprinting techniques overcome the reflected light problems, but have not been used in automotive applications, because the polymer resins designed for nano-patterning do not adhere well to the poly(methyl methacrylate) (PMMA) resin used in automotive instrument clusters.

A UV curable resin is described that has a refractive index similar to that of the PMMA and can minimise light reflection.

The coating comprises (1) a UV curable resin, (2) a photoinitiator, (3) a solvent-free additive for surface modification and (4) a weather-resistant stabiliser.

The prepared coatings are applied onto a nano-imprinting stamp and covered with a PMMA sheet. Air is removed by use of a roller and the coating irradiated with UV. The

nano-imprinting stamp is removed leaving a film having good adhesion, heat and light resistance as well as low reflectance values.

Electron beam curable composition for curing in a vacuum chamberWO 2011 084375, December 2010, Ideon LLC and Metallized Surface Technologies LLC, USA

There is commercial interest in applying protective and/or functional coatings over metallised film substrates directly inside a vacuum chamber. One benefit of EB curable compositions is that they are essentially solid and do not transfer into the gas phase under the vacuum. Advantages in coating uniformity and adhesion to the non-oxidised metal surfaces are seen.

The liquid is coated onto the substrate under a virtually oxygen-free atmosphere and the coating irradiated with an electron beam. The coating comprises an ethylenically unsaturated methacrylate monomer or oligomer (or mixtures). It is important that the composition be substantially free from ethylenically unsaturated acrylate compounds, initiators and solvents. The resulting composition can provide improved moisture and oxygen barrier properties, scratch resistance, adhesion and printability. It can be completely cured with a low voltage electron beam (up to 40kGy).

System and method for coating medical devicesWO 2011 038483, September 2010, Covalon Technologies Inc, Canada

Implanted medical devices find many uses in current clinical practice. However complications may arise from their use, such as the device acting as a focus for microbial contamination. Polymeric devices are often coated with hydrophilic polymers to create lower friction and thereby cause less damage to tissue. Coating such devices is time consuming and laborious and it is desirable to have a more efficient method of coating.

A method of photo-grafting a coating polymer onto the wet photoinitiator-coated surface of a medical device is described.

A grafting station comprises

1. A grafting tank for submerging the device in a polymerisable solution;

2. A diffuser within the tank for bubbling an oxygen scavenging gas from the solution;

3. A UV light source.

The light source is outside of the tank and

the wall is transparent to UV.The polymerisable solution typically

comprises acrylic acid and methyl methacrylate. The oxygen-scavenging gas is selected from a group containing nitrogen, argon, helium and combinations of those gases. After curing and washing the coated device is dipped into a solution of an antimicrobial agent.

ECHA updates REACH-IT and IUCLID 5ECHA has released a new version of IUCLID 5 in late May 2012 and subsequently will release new version of REACH-IT. At the same time, ECHA will start publishing more information on chemical substances. The new IUCLID 5.4 release will bring about changes mainly on how certain substance information included in the Chemical Safety Report (CSR) is reported. In addition, certain information included in the Safety Data Sheet (SDS) will be made publicly available. ECHA will publish a Question and Answer document to inform stakeholders in advance about the impact on the upcoming submissions of registration and other dossiers.

ECHA accepts group notification to the Classification and Labelling Inventory for companies who are not themselves manufacturers or importersThe European Commission has clarified that ECHA may allow third parties, such as Only Representatives (ORs) appointed under the REACH Regulation, to submit C&L notifications under Article 40 of the CLP Regulation. This is possible, provided that the importers remain responsible for the notification and the system is enforceable.

Updated Guidance on registrationThe European Chemicals Agency (ECHA) has published an updated version of the Guidance on registration following the conclusion of the consultation process. The Guidance is now available in the ‘Guidance on REACH’ section of the ECHA website.

At least 2300 substances planned for registration by 2013ECHA surveyed industry at the end of 2011 to get an accurate picture of all the phase-in substances to be registered by the 2013 deadline. This REACH registration deadline of 31 May 2013 concerns all potential registrants of phase-in substances if they manufacture or import them in the EU in quantities reaching 100 tonnes or more per year.The preliminary results of the survey published today reveal a list of 2 300 substances that will be registered for the first time by the next deadline. ECHA will update the list on a monthly basis and invites any potential registrants who intend to register by the 2013 deadline

RadTech Europe HSE Updateand whose substance is not yet on the list to inform us of their intention by answering the ECHA survey received by them at the end of 2011. Potential registrants may also consult the list of registered substances to verify whether the substance was already registered.The list of substances will also be useful for downstream users to know whether the substance that they use has already been registered or is expected to be registered by 2013. However, as the list is not linked to the specific uses of their substance, downstream users are still advised to contact their suppliers and to communicate their specific uses to make sure they will be covered in the chemical safety assessment and exposure scenarios associated with a registration. Go to http://echa.europa.eu/information-on-chemicals/registered-substances/identified-substances-for-registration-in-2013 for the list of substances intended to be registered by 31 May 2013

Dossier dissemination in progressAround 90% of all dossiers and 80% of all substances registered have been disseminated by February 2012. Information on registered substances can be found on the ECHA website at http://echa.europa.eu/information-on-chemicals/registered-substances.

Over three million submission records covering more than 90,000 chemical substances are now freely accessible from the ECHA websiteOn the 13th of February, ECHA has launched the Public Classification and Labelling (C&L) Inventory with the information coming from REACH registrations and CLP notifications so far received by the Agency.The Inventory provides a wealth of information from Industry on how they have self-classified chemicals and shows how some companies have classified the same substance differently. ECHA has not filtered or quality checked the information provided.

The Public C&L Inventory represents the largest database of self-classified substances available globally. A number of options are available for searching the Inventory, based on both the substance identity and its classification. Future updates of the Inventory will continuously improve the search functions in order to enhance access to the information.

ECHA updates the Candidate List with twenty new Substances of Very High ConcernECHA has added twenty substances to the Candidate List which now contains seventy-three substances. The Candidate List, including the substances which ECHA added to this list, is available on ECHA’s website. Companies may have legal obligations resulting from the inclusion of substances in the Candidate List which may apply to the listed substances on their own, in mixtures or in articles.Producers and importers of articles have to notify ECHA by 19 June 2012, if both of the following conditions apply: (i) the substance is present in those articles in quantities totalling over one tonne per producer or importer per year and (ii) the substance is present in those articles above a concentration of 0.1 % weight by weight. There are exemptions from the notification obligation if the substance is already registered for the use or when exposure can be excluded Information on the notification of substances in articles and related submission tools, as well as a manual with instructions on how to create and submit a notification dossier are available on ECHA´s website.Go to http://echa.europa.eu/web/guest/candidate-list-table for the candidate list EFSA announces new assessment of BPAThe European Food Safety Authority (EFSA) has started work on its new risk assessment of bisphenol A (BPA), used in food contact materials, focussing in particular on exposure of vulnerable groups. The new opinion will complement earlier scientific advice provided at the request of the European Commission.

Nordic Council issues guidance on printing inks in food packagingThe Nordic Council of Ministers has published a report on printing inks in food contact materials to guide industry, trade and food inspectors in Nordic countries. The Nordic Council is a geo-political, inter-parliamentary forum for co-operation between the Nordic countries. The report contains check-lists for declarations of compliance to aid companies from chemical manufacturers to users of printed packaging. http://www.norden.org/en/publications/publikationer/2012-521?goback=%2Egde_2297001_member_113982012

Drupa slogan from IST METZ documents move towards greater energy efficiencyNürtingen’s UV-drying system manufacturer is updating company philosophy with the new more3 slogan and turning the spotlight on energy efficiency - New “green” look for company at trade fair. When IST METZ GmbH unveils its new label “more3” for systems and services at drupa 2012, this change will represent far more than just a new look. We spoke with IST METZ Managing Director Dirk Jaegers about the new label, the background and how it all came about. Mr. Jaegers, the new logo at the side of the IST METZ lettering looks pretty impressive - what exactly does it represent? Dirk Jaegers: “We are updating our company philosophy with this new feature, which we first unveiled to the public ten years ago with the slogan “more than UV”. We see ourselves as a full service provider of solutions for UV technology, and not just a system manufacturer. This can already be seen in the comprehensive services package our customers receive together with our products.” Could you describe this “comprehensive package” in more detail? Dirk Jaegers: “From very early on, right back when we started out 35 years ago, we have placed great emphasis on internal know-how and achieving the highest standard of quality, avoiding sole reliance on suppliers. Our company group

has continued to go from strength to strength as a result, and I’m not just talking about turnover here. The IST METZ Group currently comprises 14 companies, among them highly specialised subsidiaries responsible for the essential technical progress, as well as providing the customers with the expert information they need. Take, for example, eta plus electronic gmbh where our UV lamps and electronic power supply devices are manufactured or S1 Optics GmbH, responsible for the coating of our reflectors. Our customers have access to all this expertise when looking for the right solution for their needs. Being able to provide such scope of support is one of our unique selling points.” But why then the need for the new label “more3”? What new direction has IST METZ taken that warrants this change? Dirk Jaegers: “For a start, we make it our priority to update our corporate design every four years in line with drupa. For a company in the printing industry, that not only means refreshing the website but also creating a new image brochure with which we can once again showcase the possibilities for UV and the various print substrates in the graphics sector. As part of this update, we have continued with the idea of “more than UV” and used it to emphasise our increased focus on energy efficiency: The word “more” now includes “e3”, and that stands for “energy efficient equipment”. We are also referring here to our own e3 label for new product series, which not only represent a high standard of reliability, performance and precision, but also significantly reduced energy consumption.” How will this reduced consumption be achieved? Will efficiency suffer? Dirk Jaegers: “No, the opposite in fact: the degree of efficiency is generally better than with previous models with considerably higher energy requirements. We are designing these units a more conscious aim of optimum performance and economic feasibility. That means: new electronic power supply devices, high-quality UV lamps, innovative reflector technology with optimised raytracing and a very effective reflector coating, as well as an intelligent control that makes the most of saving energy. At the end of the day, the customer receives UV drying systems with the e3 label, machinery that far exceeds the competition in terms of efficiency. Most important of all, however, is that we always take the benefit to the customer in conjunction with the degree of efficiency into consideration when developing new systems: total cost of ownership is today more important than ever when making a purchase decision. And we have

Heidelberg and Lüscher announce collaboration to jointly develop CtP platesetter with UV technologySuprasetter 106 UV - cost-effective solution comprising CtP UV platesetter, Saphira products, and Prinect workflow for customers with high plate requirements•UVtechnologyexpandsrange of applications for Suprasetter series •ProductionofSuprasetter106UVatHeidelberg site in Wiesloch-Walldorf Heidelberger Druckmaschinen AG (Heidelberg) and Lüscher AG Maschinenbau (Gretzenbach, Switzerland) have established a collaboration to develop a CtP platesetter with UV technology. Bringing together two cutting-edge technologies like this paves the way for a new member of the Suprasetter family. Heidelberg will offer the machine as a package solution comprising the Suprasetter 106 UV, conventional UV plates from the Saphira consumables range, and the prepress solutions of the Prinect print shop workflow. The Suprasetter 106 UV will be produced at the Heidelberg site in Wiesloch-Walldorf. Lüscher will be presenting the CtP platesetter in an adapted design under the name “XDrum! UV” at drupa in Hall 5, Stand B38. It will be available for customer installation in fall 2012. “With a reputation for high-quality technical solutions, Lüscher AG Maschinenbau has been delivering outstanding and state-of-the-art products for the graphic arts industry for over 60 years and is thus the ideal cooperation partner for expanding our prepress portfolio,” says Stephan Plenz, member of the Management Board responsible for Equipment at Heidelberger Druckmaschinen AG. “The UV technology expands the range of applications covered by our Suprasetter family even further. It is a particularly interesting cost-effective alternative for customers with plate requirements of over 15,000 m2 per year if the UV plate also matches the customer’s other requirements.” The plate requirements of many print shops are growing as the job structure changes. Shrinking print runs coupled with a growing number of jobs call for cost-efficient plate production, particularly for industrial print shops. “Cooperating with Heidelberg, the world’s leading supplier of solutions for sheetfed offset printing, enables us to open up a far wider customer base for our UV

platesetter technology,” says Anton Tanner, COO of Lüscher AG Maschinenbau. “Working together on the development project for the new external drum platesetter with UV technology in recent months has shown that the two companies intermesh perfectly in terms of technology and focus on innovation,” says Peter Berner, CTO of Lüscher AG Maschinenbau.BYK Additives & Instruments opens new lab building in WeselAs part of the global Marketing & Sales conference and the site’s 50th anniversary, BYK Additives & Instruments is today officially opening its ultramodern lab building in Wesel. Inside of two years’ building activity, 8,000m2 of lab space and 130 jobs have been created. Since end of 2011, some 80 lab staff have already been working there, primarily on developing innovative additives for plastics applications. In the words of Dr. Roland Peter, President Division BYK Additives & Instruments: “This new building is an integral part of our company’s innovation strategy. Because whoever is globally networked and wants to collaborate successfully on application development must create space for effective communication. The new laboratory building constitutes the ideal conditions for this due to its user-oriented planning and generous amount of space.” Particular value was placed in the planning stage on the efficient use of energy. With the aid of near-surface geothermal energy, heat pumps and heat recovery systems, primary energy consumption can be reduced by 30% against standard buildings. As regards the construction materials used, they either consist of renewable materials or are easily disposed of. Likewise, the insulation and the entire ventilation system are in compliance with the strict energy requirements. BYK Additives & Instruments has thus been able to meet all the necessary requirements for the LEED precertification (Leadership in Energy and Environmental Design) under the Platinum standard and has received the official documentation from the USGBC (Green Building Council).
