ABSTRACT:
Curative compositions of amine terminated polyamide resins blended with a deaminated bis-(p-aminocyclohexyl)methane composition (DeAms) are useful for curing adhesive epoxy resin compositions. The polyamides comprise combinations of fatty mono-acids, dimer acids, polyethyleneamines, and piperazine ring containing polyamines which are piperazine or N-aminoalkylpiperazine, where the alkyl chain is a C2 to C6 alkyl chain, wherein the ratio of equivalents of fatty mono-acid to dimer acid can range from about 0.001:1 to about 1:1, the ratio of moles of piperazine ring containing polyamine to polyethylene amine can range from about 0.1:1 to about 1:1, and the ratio of moles of polyamine to equivalents of acid can range from about 0.6:1 to about 1.2:1. DeAms is blended at 2 to 40 wt % based on polyamide. Adhesive compositions comprising these curatives are also disclosed.
