Ⅸ 、matters needing attention
1. The paint and thinners shall be sealed in a cool place to prevent fire, leakage, sun, high temperature and fire.
2. The storage period of the coating is one year. Please use it up within one year to avoid affecting the quality.
3. After the paint is opened, it shall be fully stirred evenly, and the residue at the bottom of the tank shall be mixed into the mixing tank to make the color difference of the paint sink together.
4. After the coating is thinned, filter it with a 200 mesh mesh mesh. The sprayed workpiece shall be placed in a dust-free environment for 5-10 minutes, and then put into the oven.
