The adhesion properties of amine-cured epoxy resins are unexpectedly enhanced by addition of certain amino terminated polyether ureylene 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 ureylene having terminal amino groups and a molecular weight of from about 4000 to about 4500. |
