<p>There is provided a curing agent composition for epoxy resins and two component curable epoxy resin compositions. The curing agent is made by reacting at least a b) substituted aryl amidopolyamine with a c) monoglycidyl capping agent, where the substituted aryl amidopolyamine is made by reacting at least; bi) a phenolic compound substituted with at least one carboxyl group and at least one hydrocarbyl group having at least 1 carbon atom, and bii) an aliphatic polyamine compound having at least two primary amine groups. The curing agent is storage stable for at least 6 months. There is also provided a two component epoxy resin composition, which advantageously can be made in the absence of external catalysts/accelerators, and can cure within 24 hours at the low temperature of 4.4 DEG C. The two component epoxy resin composition also exhibits excellent compatibility between the curing agent and the epoxy resin, thus reducing or eliminating the need for an induction time.</p> |
