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.
