Permafil® 707N

Permafil® 707N

Permafil® 707N solventless polyester resin is a semi-rigid resin system designated primarily for vacuum-pressure impregnation of form wound motors and generators. 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.

Key Properties

Excellent coverage and retention
Low viscosity for improved impregnation
Low weight loss during heat aging
Exceptional electrical properties
