Characteristics and uses
N-methyldicyclohexylamine is a low odor tertiary amine auxiliary catalyst for improving the skin setting of soft and rigid polyurethane foams;
N-methyldicyclohexylamine is mainly used as a cocatalyst for a foaming catalyst and a gel catalyst. The addition of 20% N-methyldicyclohexyl to the main catalyst accelerates the curing and has no effect on other properties;
N-methyldicyclohexylamine is mainly used in polyurethane rigid building materials, polyurethane rigid spray foams and polyurethane flexible foams.
