Compared with the traditional painting process, the electrostatic spraying process has a significant advantage. It does not require diluent. The coating has excellent appearance quality, strong adhesion and mechanical strength. Spraying construction curing time is short; The corrosion resistance of coating is much higher. No primer required; Simple construction, low technical requirements for workers; The cost is lower than the painting process; Some construction sites have made it clear that the electrostatic spraying process must be used. In the process of electrostatic powder spraying, there will be no common flowing phenomenon in the process of spray painting.
