Polytec TC 406 is a pasty, two component epoxy with curing at room temperature, used for thermal management in electronics, hybrid technology, sensor technology and power engineering. Polytec TC 406 has a good thermal resistance as well an excellent thermal conductivity. The application can be performed directly from the side by side cartridge with a static mixing nozzle, using a dispensing gun.

Product Type: 2K (2 component) Adhesive, Epoxy Adhesive

Processing
  • The processing of two component products from side by side cartridges is very simple
  • The cartridge is inserted into a suitable dispensing gun. The closing cap of the cartridge is then removed and replaced by an according static mixing nozzle
  • By activating the trigger of the dispensing gun, the two components are pressed out and automatically mixed in the static mixer
  • In order to prevent mixing errors, dispose the first half of the content in the mixing nozzel prior to application
  • Processing should be carried out rapidly after mixing the components as an indication, the pot life can be used
  • When the pot life is exceeded, the mixing tube should be replaced with a new one
  • Close the cartridge with the cap after use
  • Surfaces should be clean, thus free of dirt, grease, oil, dust or process chemicals
  • Please take care of respective minimum curing temperature and time

Note

*Curing temperatures refer to the temperature in the respective bond line. When choosing the respective curing conditions, the time needed to heat the substrate has to be considered. Depending on the type of heat source (convection oven, hot stamp, heating plate) the heat input may vary.
