Notes
1. If it is not a matching primer, please test the adhesion of the coating first, and confirm that it can be used in batch after meeting the requirements;
2. During the operation of this product, pay attention to the spray film thickness control to avoid vertical flow and other adverse phenomena;
3. When adding dyes, the solubility should be measured in advance, and then added to the paint after no problem;
4. If the product is stuck on the skin, rinse it immediately with water; Unused coatings should be sealed to avoid viscosity increase and stored in a dark, dry and ventilated place.
