HEMPADUR PRO 4560 has gone through

Hempel’s extensive performance test

program, including 6 months cathodic

disbondment test.

HEMPADUR PRO 4560 is ideal for

industrial and marine maintenance

applications and new constructions using

normal airless spray equipment.

HEMPADUR PRO 4560 can be applied

as both a universal primer and an

intermediate coating for high-performance

systems in atmospheric and in-water

service.

HEMPADUR PRO 4560 is a modified epoxy coating available in both summer and winter

versions, designated HEMPADUR PRO 45601 and HEMPADUR PRO 45603, respectively.

Both are available in a range of colours, in aluminium and MIO versions. The most

important single property of epoxy resin is its ability to transform readily from liquid to a

hard, resilient solid coating, regardless of the type of binder formulation used.

Professionals select HEMPADUR PRO 4560 as their universal primer of choice because

of its superb performance in submerged areas such as ballast tanks. In addition to

its inherent resilience, HEMPADUR PRO 4560 features very low water permeability

and exceptional adhesive properties. As an industrial primer or intermediate coat,

HEMPADUR PRO 4560 is easy to apply, dries fast and performs exceptionally well, even

in the harshest conditions.

HEMPADUR PRO 45601 and HEMPADUR PRO 45603 are included in systems

prequalified to NORSOK M-501 (systems 1 and 7).

How to read the Radargram• The Hempel Radargram mapping tool provides customers with a considerable amount of crucial information about

epoxy coatings in a straightforward, easy-to-understand form. The Radargram displays a range of important quantitative and qualitative product performance criteria.

• The Radargram uses a scale from 0 to 10, with 10 as the highest score. An average score of around 4 should be the minimum for an epoxy coating, unless the product has specially designed features. These are difficult to show in a Radargram, which makes general comparisons between all types of epoxy coatings.

• The Radargram is intended as an overall indication of the characteristics and capabilities of the product. The left side of the Radargram provides an indication of the general performance properties – the main focus for the end-user/ owner. The right side gives an indication of the application properties, which are of prime interest for the applicator.

• A blue Radargram indicates that the product is intended for both submerged and dry areas. A red Radargram indicates that the product is intended for dry areas.

• Read more about the Radargram in the Hempel Epoxy Encyclopaedia, in the Hempel Radargram Illustrator or at www.hempel.com.

Surface preparation St3 – Sa21⁄2HEMPADUR PRO 4560 performs extremely well on both manually

prepared and fully abrasive blasted surfaces. However, the better the

surface preparation, the better the performance of the coating.

Application temperaturesHEMPADUR PRO 4560 is best applied when the surface temperature

is above freezing point, and it should always be applied when the

air temperature is above dewpoint. The coating will cure down to a

minimum of -10°C (+14°F). HEMPADUR PRO 4560 can be applied in the

dry film thickness (DFT) range of 100–200 micron (4–8 mil).

Typical usesHEMPADUR PRO 4560 is the ideal choice as first and second coats in

any coating system or as a high-performance universal primer in both

wet and dry areas. HEMPADUR PRO 4560 can be overcoated with a

suitable topcoat if special colours or gloss retention are required, and

with a sealer/antifouling when used as the underwater primer system.

STEELSTEEL

What does aluminium pigmentation do?Aluminium in coatings can either be leafing or non-leafing. Leafing

aluminium pigments are normally used in low-solids topcoats applied

in thin coats by air spray (e.g. car paint). Leafing aluminium pigments

“float” to the surface of the coating during drying and settle in the

upper layers of the film. This imparts the paint film with a very shiny

metallic look.

Non-leafing aluminium pigments are normally used in

highly thixotropic primers applied by airless spray. These

pigments are evenly distributed throughout the entire

film thickness, which gives the paint film a grey look. In

aluminium coatings, penetration is hindered by the fact

that the penetrants (e.g. water, oxygen, ions) must work

their way around each aluminium flake.

Lamellar overlapping aluminium pigmentsThe non-leafing aluminium pigments used in HEMPADUR PRO

4560 provide an increased lamellar effect by overlapping each

other. This reduces water, oxygen and ions permeability of the coating

applied on both new as well as old steel.
