Description

CHT SE3000 is a 2-component, silicone elastomer system specially designed for electronic potting and encapsulation applications. It offers good protection against chemicals, environmental contamination, mechanical shock, vibration and impact damage. It can be employed in areas where low flammability is a prerequisite. The cured elastomer can be repaired. The component parts have relatively low viscosities and are readily mixed either by hand or machine.

Benefits

  • Thermal Conductivity = 1.2 W/mK
  • Working Temperature = -70°C to 250°C
  • Dielectric Constant = 4.53

Features

  • Thermally conductive
  • Low Viscosity
  • Low Volatility
  • UL94V-0 APPROVED FILE NO. E334038
