A Sustainable Approach to Modern Coating Technology
Patcham FZC is a well-established manufacturer of specialty additives headquartered in the United Arab Emirates. Since its inception, Patcham has steadily grown into a leading supplier of specialty additives for the Paint & Coatings, Ink, PVC and Composite industries.
The company’s Pat-Add range of coating additives includes wetting & dispersing agents, defoamers, slip & leveling agents, rheology modifiers. Whilst keeping focus on environmental sustainability, the company produces products using green raw materials that are APEO free and have low or no VOC.
These products are multi functional and multi compatible, which simplifies the production process, reduces the chance of errors and minimizes inventory thus improving cost effective-ness.
Patcham has built a strong manufacturing and R&D infrastructure that enables the rapid transition from concept to products. The company has strategically located technical service laboratories, offices and representatives around the world to provide the most efficient customer service. In addition, a well-developed robust supply chain network enables it to deliver its products and services to customers around the globe with minimal lead-time.

Optimum rheology for computerized dispensing systems
Easy incorporation, low shear should be sufficient for optimum dispersing
Pigment concentrates generally refers to any pigment dispersion used as tinting pastes or full mixing systems. Pigment concentrates contain high loading of pigments dispersed with or without a dispersing resin. Stainers, tinters, colorants, shading pastes are some of the alternate terms used.

Patcham dispersing and wetting agents in focus
The role of wetting agent is to gradually reduce the interfacial surface tension as a result of which the air entrapped on the pigment surface is replaced by the medium. This results in effective wetting of the pigment.
The process of dispersing follows Figure 3, which illustrates that dispersion requires the input of energy to break up the agglomerates into primary particles. Mechanical forces such as grinding or high speed dispersion are required for the above process. Once the particles are mechanically broken down to their primary size, stabilization of the particles takes place through the adsorption of the dispersing additives.
To ensure long term stability of the dispersed primary particles, the dispersant molecules have to be firmly adsorbed onto the pigment surface. This means that the additive require the effective pigment affinic groups or segments which can interact strongly in the pigment surface by ionic bonding, dipole-dipole interactions or hydrogen bonding.
Figure 2: Illustration of pigment wetting & dispersion
Figure 3: Pigment dispersion process Figure 4: Mechanism of pigment stabilization
The mechanism of pigment stabilization as shown in Figure 4 is either by electrostatic repulsion or steric hindrance or both. In case of water based pigment concentrates it is electrostatic repulsion and steric hindrance and in solvent borne systems it is mainly steric hindrance.
Why are wetting & dispersing agents utilized
Primary particlesDispersion
Agglomerated/�occulated particles
Pigment powder De-�occuated Primary particles
1 particle> 100,000 particles
Electrostatic repulsionSteric hindranceStabilization increases with

Resin/solvent compatible chains protruding into the surroundingvehicle.
Stabilization increases withthickness of electrical double layer
Polyelectrolytes Additives used for dispersion in waterborne systemsHigh molecular weight products containing electrical charges in side chains Polyphosphates Polycarboxylates
Pigment wetting & dispersionDuring the wetting step, air and moisture occurring on thepigment surface are driven off and replaced by the liquid of the mill-base

Patcham's innovative High Molar Volume technology dispersants are specially designed polymers with a higher volume per mass as compared to conventional high molecular weight dispersing agents.
Multiple anchoring groups and multi compatible polymeric chains make it most suitable for high structured carbon blacks, organic pigments and wide range of resin systems
Key features of High Molar Volume technology : Dense network of anchoring groups provides best wetting of pigments
Optimum mill base viscosity and reduced milling time
High jetness and blue under tone Provides excellent long term stability of pigment dispersions
Superior gloss and transparency

Pigment concentrates are color pigments dispersed in a blend of wetting and dispersing additives and a liquid carrier. The level of pigment incorporated is dependent on the color strength required and limitations based on pigment surface area. An important criterion for the additives present in universal pigment concentrate should be their compatibility with waterborne and solventborne architectural bases.

Patcham has a range of additives from which two unique choices are highlighted for solvent based alkyd system:
• Pat-Add DA 1803 for resin free pigment concentrates • Pat-Add DA 1808 for resin minimal pigment concentrates based on alkyd resin
The pigment concentrates made with these dispersing agents show excellent compatibility and minimize the risk of flooding and floatation. Another advantage of these additives can be seen in the long term stability of the pigment concentrate.

Industrial pigment concentrates
Main benefits are:
Pat-Add DA 932
The suitable dispersant for high pigment loaded tinters
Effective for furnace carbon blacks, for extreme jet, blue undertone
Provides excellent color development and transparency
For wood coatings, refinishes, general industrial coatings, pigment concentrates
Solvent based pigment concentrates
High Molar Volume technology for use in industrial solventborne paints and pigment concentrates.
Strong adsorption properties make it suitable for use in a wide variety ofpigment surfaces
Best dispersion stability, low viscosity pigment dispersions and high transparency fir fine particle sized pigments.

This is a solvent free wetting and dispersing additive for solventborne and solvent free coating systems, PVC plastisols, thermoplastic and adhesives. It stabilizes organic and inorganic pigments, particularly carbon blacks.
It is particularly suitable for the production of polyol pastes for PU as well as PVC applications. Anti-separation additive for SMC/BMC formulations. Pat-Add DA 815 creates Newtonian flow behavior of the material by reducing the viscosity drastically. It can also work as a neutralizer for acidic and neutral carbon black pigment.
Solvent free pigment concentrates
Pat-Add DA 815
Key benefits
• Provides excellent uniformity and color development
• Improves torque build up and filter pressure value
• Reduces viscosity
• Longer shelf life of colorants
