A curable epoxy resin composition comprising (A) an epoxy resin; (B) a thixotropic agent in an amount sufficient to induce thixotropic properties, and a hardener comprising (C) at least one polyethyleneimine and (D) at least one other amine having at least 2 amino hydrogen atoms, the combined amounts of (C) and (D) being sufficient to effect cure of the epoxy resin, said amine (D) being selected from the group consisting of alkylenediamines, polyalkylenepolyamines, N-hydroxyalkyl derivatives of polyalkylene polyamines, polyoxyalkylenepolyamines, N,N-dialkylalkylenediamines, cycloaliphatic amines having an amino or aminoalkyl group attached to the ring, aromatic amines, amine-terminated adducts of epoxy resins with aliphatic, cycloaliphatic or araliphatic amines as hereinbefore described, N-aminoalkyl-piperazines and polyaminoamides, the combined amounts of (C) and (D) being sufficient to effect cure of the epoxy resin. |
