Adhesives/Sealants,Thermally Conductive

Low Volatility Thermally Conductive Silicone Adhesive

DESCRIPTION
  • Two-part, white, thermally conductive, electrically insulating, silicone system
  • Electrically insulative and non-corrosive
  • 15:1 Mix Ratio (Part A: Part B)
APPLICATION
  • Flexible Thermal interface material (TIM) designed to provide heat transfer between electrical/electronic components and their heat sinks for a variety of component level packaging
  • For applications requiring a broad operating temperature range
  • Ideal where a form-in-place TIM is needed for use as a sealing, caulking, adhesive, or potting material in electronics applications requiring minimal volatility for prevention of contamination in sensitive devices
