Polyamidoamine curing agents based on mixtures of fatty and aromatic carboxylic acids |
摘要 |
Compositions of amine terminated polyamidoamine resins useful for curing epoxy resins are disclosed comprising combinations of fatty monocarboxylic acids, aromatic mono- and dicarboxylic acids, and polyethyleneamines, wherein the ratio of equivalents of fatty monocarboxylic acid to aromatic monocarboxylic acid can range from about 1:0.2 to about 1:1.5, the ratio of equivalents of monocarboxylic acids to aromatic dicarboxylic acid can range from about 1:0.1 to about 1:0.6, and the ratio of moles of total polyamine to equivalents of total acid can range from about 0.8:1 to about 1.3:1. Coating compositions comprising these polyamidoamine resins are also disclosed.
