Polyether diureide epoxy additives

摘要

The adhesion properties of amine-cured epoxy resins are unexpectedly enhanced by addition of certain polyether diureide 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 diureide having terminal ureido or monosubstituted ureido groups and a molecular weight of from about 2000 to about 3000.
