The role of metal surface treatment is mainly to improve the adhesion of the coating to the surface of the material, improve the corrosion protection of the paint layer on the metal substrate, and improve the flatness of the substrate surface. When some contaminants such as oil, grease, dust, etc. are attached to the substrate, the coating will not adhere well, causing the paint film to fall off or produce various appearance defects. Therefore, all substrates to be painted need surface treatment to increase their corrosion resistance and durability, so as to give full play to the role of the coating. The quality of surface treatment directly affects the adhesion of the coating to the substrate and the corrosion resistance of the material.

As a high-quality product widely used in industrial anti-corrosion, the main advantage of low-surface treatment coatings is that it has excellent anti-corrosion performance, weather resistance, environmental protection performance, coating performance, etc., especially suitable for steel anti-corrosion that is difficult to surface treatment.
The coating treatment of general anti-corrosion coatings requires that the surface cleanliness of the substrate reach Sa2.5 level or above, which is a relatively thorough surface treatment. When it is impossible to fully reach the sandblasting level, but also to meet the high level of anti-corrosion protection requirements, low surface treatment anti-corrosion coatings are required. It should be noted that the low-surface finish coatings should be able to be applied to different types of old coatings without compatibility problems.
