Thermally Conductive Silicone Potting Compounds

TIM-PC Series

Product Description:

Thermally Conductive, two parts, low viscosity potting compound that cures at room temperature to a soft pliable rubber. Will cure in deep sections. Designed to achieve primerless adhesion to many substrates, including metals, plastics, and ceramics. The excellent electrical properties make it a candidate material for both high and low voltage electrical assemblies.

Typical Applications:

Potting and encapsulating of:

  • Equipment modules, Power supplies, relays and amplifiers, Transformers, coils and ferrite cores
  • Fiber optic wave guide coatings
  • Encapsulation of circuit boards
