About Polytec PT Thermally Conductive Adhesives in Cartridges

Polytec PT Thermally Conductive Adhesives are packed in 50ml side-by-side cartridges for convenient manual processing. Polytec TC 406, Polytec TC 411 and Polytec TC 422 are two-component epoxies that cure at room temperature and are used for thermal management in electronics assembly, hybrid circuits, sensor manufacture and power engineering.

  • Polytec TC 406 offers some of highest thermal conductivity available in cartridge-packaged epoxies (2.2 W/mK)
  • Polytec TC 411 has very good thermal conductivity (1.4 W/mK) alongside a Shore D 38 hardness for extra flexibility and resilience
  • Polytec TC 422 offers an easy-to-process 50,000 cP viscosity for good flow characteristics

We also offer several other thermally conductive adhesives from Polytec, supplied in bulk containers, twin-packs, or premixed and frozen syringes.
