hdi trimer hi-190
about:
aliphatic polyisocyanate based on isocyanurate-modified hexamethylene diisocyanate (hdi). exhibits excellent weather and chemical resistance, non-yellowing and physical properties. it is an approximately 90% solids solution in a 1:1 blend of n-butyl acetate and solvesso 100. can be diluted with esters, ketones, glycolether acetates or with aromatic hydrocarbons. used to crosslink most hydroxy-containing resins and hydroxy functional polyesters. recommended for
the formulation of lightfast and weather-resistant two-pack polyurethane coatings. suitable for interior & exterior general industrial metal coating, plastic component coating, wood coatings for floor, furniture or millwork, and automotive oem or refinish applications. it is listed with tsca, epcra 311/312 and epcra 313.
