Curing agents providing a low ratio of thin-film cure time to gel time

摘要

The present disclosure relates to a curing agent for a curable resin which is a reaction product obtained from the reaction of a liquid epoxy and a polyamine component. The curing agent may be used as part of a two component curable system for the curing of unmodified epoxy resins.

主权项

1. A two component curable system comprising:
(A) a curable component comprising an epoxy resin; and (B) a curing agent component comprising a reaction product obtained from the reaction of a liquid epoxy and a polyamine component consisting of a cycloaliphatic polyamine compound having the formula (1)where R and R1 are, in each instance independently of one another hydrogen or a linear or branched C1-C5 alkyl group; X is a C6-C20 cycloaliphatic radical; a is an integer from 1-5; and b is an integer from 1-5.
