Abstract
Latent, heat-curable epoxy resin compositions containing metal carboxylate curing systems provide exceptional latency, particularly at elevated temperature, as well as facile curing, high T.sub.g and adhesive strength, and other attractive properties. The metal carboxylates comprise alkali metals and alkaline earth metals, aromatic and aliphatic metal carboxylates. The preferred curing systems comprise synergistic combinations of the metal carboxylates with cure modifiers.
