Generators & Motors

Araldite® and Aradur® casting and impregnation systems can be used in virtually all insulation components of motors and generators thanks to their high mechanical strength, strong adhesion to various metals and substrates, and their excellent dielectric properties. Their low viscosity provides an excellent impregnation to the electrical parts. The trend towards generators and motors with increased power output, higher integration density and reduced size requires materials with very high temperature resistance and which can withstand extreme thermal cycling during service.
