Abstract

Adducts which are obtainable by reacting cycloaliphatic or heterocycloaliphatic polyamines containing at least two primary groups with polyfunctional epoxides containing more than two epoxy groups per molecule in such amounts as to supply 10-100 equivalents of active hydrogen atoms bound to amino nitrogen per one epoxide equivalent, are suitable hardeners for epoxy adhesives, especially adhesives for metals and thermosetting plastics.
