ABSTRACT:
The adhesion properties of amine-cured epoxy resins are unexpectedly enhanced by addition of certain amino terminated polyether succinimide additives. The adhesively superior epoxy resin composition comprises a vicinal polyepoxide, a curing amount of an amine curing agent, and an effective amount of a polyether succinimide having terminal amino groups and a molecular weight of from about 4000 to about 4500.
