Abstract

There is disclosed a self-disbursing curable epoxy resin composition comprising the addition product of reactants comprising (a) 1.0 reactive equivalent of an epoxy resin, (b) from about 0.40 to 0.95 reactive equivalents of a polyhydric phenol, and (c) from about 0.005 to 0.5 reactive equivalents of an amine-epoxy adduct comprising the addition product of reactants comprising 1.0 reactive equivalent of an aromatic polyepoxide and from about 0.3 to 0.9 reactive equivalents of a polyoxyalkyleneamine.
