(2 component, thermally conductive silicone rubber with adhesion function)

SilCool™ TIA219R is a two-component, heat curable silicone rubber designed for thermally conductive applications from Momentive Performance Materials.

SilCool™ TIA219R cures with heat to form an elastic, thermally conductive rubber and adheres well to various types of materials such as metals, plastics, glass and ceramics without the use of primers.

SilCool™ TIA219R quickly cures with exposure to heat to a soft rubber that helps relieve stress on critical electronic components

TIA2165GF Thermally, SilCool* TIA219R Thermally Conductive Compound

Key Features

  • Soft, elastomeric rubber properties
  • Convenient 1:1 mix ratio by weight
  • Outstanding stress relief
  • Heat accelerated or room temperature cure
  • Excellent thermal conductivity
  • Resistance to temperature extremes
  • Primerless adhesion to many types of substrates
  • Non corrosive to metal
