Usage
1. The gluing surface should be free of oil stains, dust, impurities, etc.;
2. According to the process requirements, the paint will be evenly sprayed, and the thinnest part is greater than 1mm; When using a pneumatic gun, the air pressure is controlled at 0.2-0.4Mpa;
3. Curing process: 160~180°C for 30min, it can be completely cured;
4. After curing, the product can be trimmed using traditional methods.
Precautions
1. Avoid applying it in an environment below 5°C
2. It must be stored in a low temperature and dry environment with a shelf life of 3 months.
