ABSTRACT:
A process for accelerating the cure rate of a mixture comprising an epoxy resin and an amine hardener comprising including in the mixture from 0.5% to 15% by weight of a catalyst which is the reaction product of a bicyclic amide acetal and ammonium thiocyanate and curing the resulting mixture at a temperature of from about abient temperature to about 120.degree. C. is described.
