ABSTRACT:
The adhesion properties of amine-cured epoxy resins are unexpectedly enhanced by addition of certain diamides of polyoxyalkylenepolyamine-urea condensates. The adhesively superior epoxy resin composition comprises a vicinal polyepoxide, a curing amount of an amine curing agent, and an effective amount of a diamide of a polyoxyalkylenepolyamine-urea condensate having a molecular weight of from 4000 to about 4500.
