ABSTRACT:
Described herein are resinous compositions comprising a particular cycloaliphatic epoxy resin and the adduct of these epoxy resins with an aromatic active hydrogen-containing compound. These compositions afford unreinforced castings with higher heat deflection temperatures, faster cure rates, and reduced water uptake than similar compositions containing epoxy adducts made from aliphatic polyols.
