Polyamide curing agents based on mixtures of polyethyleneamines and piperazine derivatives |
摘要 |
<p>Compositions of amine terminated polyamide resins useful for curing epoxy resins are disclosed comprising combinations of fatty mono-acids, dimer acids, polyethyleneamines, and piperazine ring containing polyamines having an N-H functionality of 2 or 3 per mole selected from the group consisting of 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. Coating compositions comprising these polyamide resins are also disclosed.</p> |
