Abstract
A composition including an amidoamine curing agent composition or a polyamide curing agent composition are disclosed. The composition includes the reaction products of (1) an amine component including at least one multifunctional amine of structure (I): wherein each R is independently H or CH2CH2CH2NH2; R1 is H, CH3CH2CH2N—, C1-C21 alkyl, or C1-C21 alkenyl; n is 2; and m is 1 or 2, with (2) a fatty acid or ester component selected from the group consisting of a dimer fatty acid or ester component, a monofunctional fatty acid or ester component, and combinations thereof. The amidoamine curing agent composition remains as liquid at ambient temperature.
