Urethane polymn catalyst - comprising mixt of N-methyl-dicyclohexylamine and N,N-dimethyl-cyclohexylamine

摘要

Catalyst for making polyurethanes consists of N-methyl-dicyclohexylamine and N,N-dimethyl-cyclohexylamine in the wt. ratio 1:9 to 9:1, pref. 1:3 to 3:1. The mixt. shows better cure, gelation and rise time than either component alone while at the same time the physical props of the resulting foam are almost identical.
