ABSTRACT:
The adhesion properties of amine-cured epoxy resins are enhanced by addition of certain polyether diureide additives in combination with specific amine curing agents. The adhesively superior epoxy resin composition comprises a vincinal polyepoxide, a curing amount of an aminopropyl ethylenediamine curing agent, and an effective amount of a polyether diureide having terminal ureido or monosubstituted ureido groups and a molecular weight of from about 2000 to about 3000.
