Thermally Conductive Silicone Encapsulants

SILCOTHERM® Silicone potting materials with thermal conductivity can be used to dissipate heat away from a component to a suitable heat sink.

Addition cure silicones will provide deep section cure allowing for complete encapsulation for envronmental protection while maintaing an effective heat path.
