Thermally Conductive Silicone Potting

Thermally Conductive Silicone Potting

  • TIA208R is a fast cure (2 component room temperature curable) thermally conductive potting material for electronic applications in addition to providing low viscosity thermal potting,
  • TIA208R has the unique benefit of providing primerless adhesion when cured at both elevated heat or at room temperature, to not only metallic substrates, but to also difficult to adhere plastics such as Poly-Carbonate.
  • TIA208R’s adhesion capabilities are especially important for electronic potting applications that require IP standard water ingress performance.

Key Features

  • Primerless adhesion to metals and plastics
  • Good thermal conductivity (0.7 W/m∙K)
  • Easy to use 1:1 mixing ratio
  • Cures and adheres quickly with heat or at room temperature
  • Flame retardant : UL94V-0
  • UL RTI : 150°C

Key Applications

  • LED Ballasts
  • DC/DC Converters
  • Micro-Inverters
  • Automotive EV
  • Water ingress resistant electronic potting

Curing Behaviour

  • Although curing is possible at various temperatures, higher temperatures result in higher hardness and adhesion strength build.
  • Even when cured in ovens for 30 minutes there is a gradual increase in hardness and adhesion strength that continues for approximately 7 days.
