PC41 Highly active trimerization catalyst for polyurethane rigid foams with excellent foaming/gelling ability, usually shared with other catalysts.

PC41 is mainly used to catalyze polyurethane and polyisocyanate reactions, in fact, the catalytic selectivity for polyurethane is slightly higher than that for polyisocyanate reactions, and it is commonly used in laminate polyurethane rigid foams, sprayed rigid foams, and molded rigid foams;

PC41 is more suitable for polyisocyanate rigid foam sheet, all kinds of foaming agent foaming (including all-water foaming) and other processes, and has excellent performance in water foaming rigid foam system;

PC41 is also suitable for microcellular polyurethane elastomer and high resilience foam products.

Storage and transportation:
