The main difference between anti-graffiti powder coating and other products is that the surface coated by it can form a dense low surface energy structure, which makes it difficult for pollutants to adhere to the surface of the paint film and penetrate into it, thus obtaining a better anti-graffiti effect. Easy to wipe powder coating should not only reduce its own adhesion, but also consider how to separate pollutants from the interface of the substrate. These factors include the wettability of the substrate, the attraction between atoms and the mutual diffusion between molecules.

Easy to clean and anti-graffiti powder coating can be divided into sacrificial anti-graffiti coating, semi-permanent anti-graffiti coating and permanent anti-graffiti coating according to its protective characteristics. Sacrificial and semi-permanent anti-graffiti paint is usually composed of wax, which is removed together with pollutants. The biggest problem of this method is that the cleaning effect will deteriorate with the removal times. Permanent, long-acting powder coating has a long coating life. Using safe neutral detergent can remove graffiti, stickers or other pollutants on the coating surface for many times without losing the performance of the coating itself.

Permanent easy-to-erase, graffiti resistant powder coating has the following common characteristics:
(1) The surface energy of the coating is low, which is hydrophobic and oil repellent, and graffiti is difficult to adhere;
(2) Easy to remove contaminants adhering to the surface;
(3) The coating has certain anti-corrosion and anti-aging properties, and can be used outdoors;
