Permafil® 711

Permafil® 711

Permafil® 711 solventless polyester resin is a very thixotropic yet semi-rigid resin system designated primarily for vacuum-pressure impregnation of field coils, transformers and random wound motors where a maximum of build, gap filling and retention is required. It is a companion product to Permafil® 707. Its high thermal capability coupled with its excellent electrical properties over a wide temperature range make this resin useful in many unusual applications.
