ZIGO sign-What is metal spray painting process? What is the process of spray painting technology?

Metal surface painting is a method of protecting metals from oxidation and corrosion. The corrosion phenomenon that occurs around us refers to the damage, performance degradation, or deterioration of various materials under the combined effects of chemical, electrochemical, and several physical factors in the environment. Spraying paint on metal surfaces is an important means of maintaining metal corrosion resistance. A good spray painting protective layer maintains continuity, integrity, and good adhesion, which can become a barrier to inhibit the invasion of corrosive media.

Advertising metal spray painting process：

Surface cleaning → Spray the first layer of primer → Apply the first layer of putty → Scrub paper → Apply the second layer of putty → Sandpaper polishing → Spray the second layer of primer → Apply the third layer of putty → Sandpaper polishing → Spray the third layer of primer → Sandpaper polishing → Spray the first layer of topcoat → Sandpaper polishing → Spray the second layer of topcoat → Sandpaper polishing → Spray the third layer of topcoat → Spray a layer of varnish (gloss or matte).
