Q:What is the reason why the coating is curled, stressed, brittle, and turns blue?

1. Regarding the curling phenomenon of the coating: ① The coating is curled because there are more second-class gloss agents. ② The coating is involuted due to the excessive amount of a type of gloss agent.

2. Regarding the fragility of the coating: ① The second-category gloss agent is too high. ② Out of proportion.

3. Regarding the coating becoming black, and the edges being burnt: DK is too large.

4. Regarding the coating turning blue, and the bonding force in the recessed hole being poor: DK is too small.

"DK" means "Dry Kiln."
