HDI trimer BASF 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.
