Abstract
This invention relates to improved polyepoxide resins having enhanced physical and elastic properties. The polyepoxide resins comprise a polyepoxide resin based on a polyglycidyl ether of a phenolic-type compound and an amine curing agent. The improvement in the polyepoxide resin formulation comprises incorporating an aliphatic, aliphatic ether or ester component having monofunctional reactivity with an amine hydrogen, an amine curative having from 3 to 10, and preferably 3 to 5 epoxide reactive hydrogen atoms into the epoxy resin, and a diglycidyl ether of a polyalkyleneoxide. The presence of the monofunctional and aliphatic amine reactive component along with the diglycidyl ether of a polyalkyleneoxide results in an epoxy resin having enhanced properties.
