The four elements that make up the coating for surface spray (plastic parts) include:
1. resin
2. pigment
3. solvent
4. Other additives
The types of surface spray coating drying are as follows:
1. 2. Evaporation and drying (evaporating and drying with diluent); 2. 3. Fusion drying (molecules and molecules resist phase polymerization due to volatilization); 4. Oxidative drying (unsaturated fatty acids combined with oxygen in the air); 4. Drying by bridging reaction (using bridging agent, so-called hardener to form bridging and hardening); Ultraviolet curing (unsaturated polyesters are added with an agent and then irradiated with ultraviolet wavelengths of 300-400mn, and then the molecules are polymerized and cured).
