Polytec TC 422
- Chemical Family
- Epoxy & Epoxy Derivatives
Polytec TC 422 is a pasty, two component adhesive for thermal management in electronics, hybrid technology, sensor technology and power engineering. Polytec TC 422 has a great thermal conductivity and an excellent adhesion, especially to metals such as aluminum and stainless steel. It is also characterized by its high mechanical strength and thermal resistance. The application can be performed directly from the side-by-side cartridge with a static mixing tube, using a dispensing gun.

- 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
