Beschreibung
Zusammenfassung:	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 acrylate-terminated urethane prepolymer. The improvement in the polyepoxide resin formulation comprises incorporating a polymethylated amine curative having two secondary amine hydrogens represented by the formula:wherein R is alkylene or polyalkylene polyamine having from 2 to 20 carbon atoms. The presence of the aliphatic amine reactive component along with the acrylate-terminated urethane prepolymer results in an epoxy resin having enhanced properties.
