RESIN COMPOSITION FOR IMPREGNATION

摘要

PROBLEM TO BE SOLVED: To provide a resin composition for impregnation having highly persistent heat resistance and strong adhesiveness at a high temperature. SOLUTION: The resin composition for impregnation is produced by adding 25 wt% epoxy acrylate, especially novolac type epoxy to 75 wt% mixed resin of a polyester resin with an epoxy resin conventionally used for coils of big high voltage rotative equipment. Adhesiveness and the like at the high temperature is enhanced by using the resin composition for impregnation without reducing basic characteristics of the conventional resin.
