Proposed Dosages

Wood and furniture coatings Waterborne and solvent industrial coatings Automotive coatings Radiation-curing printing inks and overprint varnishes based on the epoxy resin (cationic curing) leather coats based on polyurethane, acrylic and nitrocellulose binders
IR-125 0.05-0.5% 0.05-0.3% 0.03-0.2% 0.05-1% 0.1-1.0%
The above-recommended dosages strongly depend on pigment particle size. Optimal dosages should be calculated in the laboratory according to a different formula.

Addition Methods&Process Technology Instructions
