ARALDITE® CW 229 / ARADUR® HW 229

ARALDITE® CW 229 / ARADUR® HW 229 can be used in all insulation components of motors and generators due to their high mechanical strength, strong adhesion to various metals and substrates, and excellent dielectric properties. The low resin viscosity ensures homogeneous impregnation. The materials have very high temperature resistance and withstand extreme thermal cycling in service. The trend toward increased power output, higher integration density, and decreased size for generators and motors requires thermal management. Our heat-conductive products are the ideal solution to dissipate the heat.
