These properties are provided as typical properties, NOT THE PRODUCTS TECHNICAL INDEX.

Proposed Dosages

	2-pack coatings based on acrylic/isocyanate and polyester/isocyanate;  1-3 %, based on total formulation
IR-1500/1530

The above recommended dosages strongly depend on pigment particle size. Optimal dosages should be calculated in the laboratory according to different formula.

Addition Methods&Process Technology Instructions

- Test the compatibility with binder.
- Add under intense agitation (agitator) in varnish formulations
- Recommend to add during grind stage in pigmented formulations.

Dilution

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

Package and Storage

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