ABSTRACT OF THE DISCLOSURE The agents comprise a mixture of (A) an adduct of a polyethylenepolyamine or a polypropylenepolyamine with an aliphatic or aromatic diglycidy] ether and (B) an aminoalcohol containing at least two aliphatic amino-hydrogen atoms, especially an adduct of a poly(aminoamide) with certain monoepoxides. A) has the formula Image and B) the formula Image where R1 represents a C2-C60 hydrocarbon radical having amino or amido nitrogen in the chain, optionally substituted by amino or alcoholic hydroxy groups, being such that B) contains at least two aliphatic amion- nitrogen hydrogen atoms, R2 represents Image R3 represent the residue (mol. weight 56 to 50,000) of an at least dihydric alcohol or phenol, p is an integer of average value 1 to 1.5, q is an integer of 1 to 5, R4 represents a hydrogen atom, C1-C3 alkyl, phenyl, cresyl, chlorophenyl group, or a group a R5OCH2-, R5 represents a C1-C18 residue of a monohydric aliphatic, cycloaliphatic, or araliphatic alcohol or of a monohydric phenol and R6 is a hydrogen atom or a methyl group. These agents are valuable hardeners for epoxy resins, whereby the curable epoxy resin mixture cures rapidly at room temperature to give chemically-resistant, hard, glossy finishes.
