Permafil® 777

Permafil® 777 solventless polyester resin is a thixotropic semi-rigid resin system designated primarily for vacuum-pressure impregnation of both form wound and random wound motors. Its high thermal capability coupled with its excellent electrical properties over a wide temperature range make this resin system suitable for both AC and DC applications.
