Abstract: WHERE N IS A WHOLE NUMBER, AT LEAST 2, PREFERABLY 2 OR 3, R stands for a n-valent aliphatic residue which may be interrupted by oxygen atoms and A represents the residue of a glycol or of a polyglycol whose terminal hydroxyl groups have been removed, and (2) the diglycidyl ether of a glycol or polyglycol.

Abstract: Curable molding, coating and adhesive compositions which contain a polyepoxide compound, for example a liquid polyglycidyl ether of bisphenol A, and, as the curing agent, an N,N'' -di-( gamma aminopropyl)-hydantoin, for example 1,3-di-( gamma -aminopropyl)5,5-dimethyl-hydantoin. Curing can be carried out at relatively low temperatures, for example at 40* C. The new type of curing agent bridges, in respect of its gradation of reactivity, a gap between aliphatic polyamines and cycloaliphatic polyamines. The new curing agents furthermore have the advantage relative to the aromatic polyamines of being nontoxic.
