Abstract:
1. Curing agent for epoxy resins consisting of, A) 1-99 wt % of an adduct obtained by reaction of a1) ethylene diamine or polyethylene polyamine having up to five nitrogen atoms in the molecule, with a2) a monoglycidylether, wherein the adduct of a1) and a2) is isolated by removing the excessive ethylene diamine or polyethylene polyamine, and B) 99-1 wt % of at least one amine compound having at least one reactive amine hydrogen atom in the molecule selected from the group consisting of piperazine, N-aminoethylpiperazine, isophorone diamine, 1,2-diaminocyclohexane, 1,3-diaminocyclohexane, 1,4-diaminocyclohexane, aminopropylcyclohexyl amine, tricyclododecane diamine, xylene diamine, propylene diamine, hexamethylene diamine, 2,2,4-trimethylhexamethylene diamine, 2,4,4-trimethylhexamethylene diamine, 2-methylpentamethylene diamine, 1,7-diamino-4-oxaheptane, 1,10-diamino-4,7-dioxydecane, 1,14-diamino-4,7,10-trioxatetradecane, 1,20-diamino-4-17-dioxyeicosane, 1,12-diamino-4,9-dioxadodecane, ether diamines based on propoxylated diols, triols and polyols, dipropylene triamine and tripropylene tetramine.
