Typical Properties:

Density at 20°C, g/mlNon-volatile matter, %Water content, %Hydroxyl value calculated on non-volatile content, mg KOH/g
These properties are provided as typical properties. Not the product technical index.

Proposed Dosages:

Dosage based upon total formulation, %
IR-1500/15302-pack coatings based on acrylic/isocyanate and polyester/isocyanate;
1-3 %, based on total formulation.
The above-recommended dosages strongly depend on pigment particle size. Therefore, the laboratory should calculate optimal dosages according to a different formula.

Addition Methods&Process Technology Instructions:

– Test the compatibility with a binder.
– Add under intense agitation (agitator) in varnish formulations.
– Recommend adding during the grind stage in pigmented formulations.


– Dilutable in esters, ketones, and glycol ethers.
– When diluting with aromatic solvents (toluene, xylene, Solvesso 100), add isobutanol or ketones with the aromatics at a ratio of 9:1.

Packing and Storage:

Packed in iron drums of 25 kg or 200 kg net each. The validity period is 12 months in sealed containers.
