  • heat coupling of power semiconductors with heat sinks
  • heat coupling of peltier elements with heat sinks

TCSA-1530

Thermally very well conductive single-component silicone adhesive with very high mechanical tensile strength, electrically isolating, curing by humidity, permanently elastic, extremely large temperature range.

  • sticking power semiconductors and Peltier elements on heat sinks
  • sticking together heat sinks

TCSG-1500

Thermally very well conductive single-component silicone gel with very high electric isolation, permanently elastic, equals unevenness, extremely large temperature range

  • sticking power semiconductors and Peltier elements on heat sinks
  • sticking together heat sinks

TCSA-0770

Thermally very well conductive two-component silicone casting mass with high mechanical tensile strength and electric isolation, hot-curing and permanent elastic, extremely large temperature range:

  • sticking power semiconductors and Peltier elements together on heat sinks
  • sticking together heat sinks
  • filling high voltage devices of high energy dissipation

PUSA-0100

Thermally ill-conductive single-component PU adhesive, electrically insulating, extended industrial temperature range, hygroscopic, directly processable

  • sealing of peltier elements for protection against condensation water
  • sealing of bolted connections
  • connection of housing components
