Abstract
Abstract Resin composition useful as a wire coating comprising the reaction product of a reactive hydantoin based compound, a polycarboxylic acid, and tris (2-hydroxyethyl) isocyanurate. The resin provides a low cost, cured enamel for electrical conductors. Preferably, the resin composition includes another polyhydric alcohol such as ethylene glycol to impart flexibility.
