Adhesives/Sealants,Thermally Conductive

Thermally Conductive Non-Corrosive Rtv Silicone Adhesive

  • One-Part, white RTV silicone
  • Non-slumping in thin sections
  • To provide moderate heat transfer between electrical/electronic components and their heat sinks
  • As a sealing, caulking, adhesive or potting material in electronics applications requiring minimal outgassing to avoid condensation in sensitive devices
  • Use for any application where grooves and other configurations require a non-slumping, non-flowable to limited flow one-part material
  • For applications requiring a broader operating temperature range
