Abstract: A PREFORMED ELECTRICAL COIL IS HEATED AND IMMERSED IN A BATH OF A STAGE EPOXY RESIN. THE COIL IS THEN IMMERSED IN A FLUID BED OFMICA POWDER UNTIL THE RESIN COAT ING BECOMES IMPREGNATED WITH MICA TO THE EXTRACT OF APPROXIMATELY 45% MICA. AFTER THE RESIN-MICA COATED COIL ISCURED AT A TEMPERATURE DETERMINED BY THE CURING TEMPERATURE OF THE EPOXY RESIN, IT IS IMMERSED IN A BATH OF A STAGE POLYESTER RESIN. THE POLYESTER COATED COIL IS AGAIN IMMERSED IN THE FLUID BED OFMICA POWDER TOPR PROVIDE A MICA COATING THEREON AND IS THEN DRIED AT ROOM TEMPERATURE.
