Abstract
A hydrolytically stable heat curable composition useful as a hermetic varnish for electrical conductors is provided. It consists essentially of an aqueous solution of (1) an epoxy adduct which is the reaction product of PA0 (A) a glycidyl ether of a dihydric phenol, PA0 (B) aminobenzoic acid, PA0 (C) a water soluble organic solvent boiling about 150.degree. C., and PA0 (D) a water soluble amine, and (2) a water soluble phenolic cross-linking agent.
