ABSTRACT:
Novel thermoplastic curing agents formed by reacting an imidazole compound with an epoxy resin, and with--optionally as a third reactant--polyfunctional proton-donating compounds like polybasic acids or phenolic novolac resins. The curing agents are extraordinary in that they are useful in formulating novel storeable, one-package, heat-curable epoxy resin-based compositions. Moreover, they react synergistically with known curing agents, most notably dicyandiamid. The cured materials are of excellent quality. Processes, whereby the various novel materials of the invention are made, are also described.
