Permafil® 712

Permafil® 712

Permafil® 712 is a solventless, unsaturated polyester resin developed for use in dip and bake or VPI tanks to replace low flash point solvent type varnishes where flammability and VOC emissions are of a prime concern.

Key Properties

High flash point, very low VOC emissions
High bond strength for lower vibration noise and for high speed rotating devices
Stable at room temperature
Lower weight loss than other similar formulations for reduced shrinkage and longer machine life
Low build for reduced clean up
Low viscosity for improved penetration
UL 1446 system recognition up to 240ºC
