COOLTHERM EP-6008

Main features

  • 8,000 cP Resin Viscosity
  • 1-Hour Working Window
  • 0.3 W/(m K) Thermal Interface

Product Description

CoolTherm® EP-6008 BLK Epoxy Resin is a black, filled epoxy resin formulated for use with compatible CoolTherm® or Thermoset™ hardeners to create two-component potting and encapsulation systems. The material is designed to flow around intricate and densely packaged circuitry while forming a rigid, electrically insulating cured compound. When combined with CoolTherm EP-6010 Hardener, the system provides a typical cured thermal conductivity of 0.3 W/m·K, a working life of 1 hour at 25 °C, and documented operating-temperature capability from -55 to 155 °C.

Key features

  • General-purpose encapsulation: Forms a two-component epoxy compound for potting and encapsulating intricate or densely packaged circuitry.
  • Low-viscosity resin: The resin has a typical viscosity of 8,000 cP at 25 °C to support flow around electronic components.
  • Electrical and thermal performance: The cured EP-6008 BLK/EP-6010 system provides typical thermal conductivity of 0.3 W/m·K and dielectric strength of 17.7 kV/mm.

Applications / Suitable for

  • General-purpose electronic potting and encapsulation
  • Intricate and densely packaged circuitry
  • Electrical assemblies requiring rigid, electrically insulating encapsulation
