The anti-graffiti easy-to-clean coating belongs to the isolation protective coating, which can prevent graffiti pollutants from penetrating into the protected material. Compared with conventional coatings, its surface energy is low, and it is difficult to adhere to pollutants and easy to remove. There are two types of anti-graffiti paint: sacrificial paint and durable paint. The former has no effect after being painted once and needs to be painted again. This kind of paint is usually made of wax or wax plus silicone; The latter is generally a cross-linked curing coating. The coating can be removed by repeated graffiti, and the effect will not be significantly reduced, and the anti-graffiti function can be maintained for a long time.

The common anti-graffiti and easy-cleaning coatings on the market mainly include organosilicon or fluorine-modified polyurethane coating, fluororesin coating, silicone resin coating, fluorosilicone coating, etc. Silicone modified hydroxyacrylic resin is synthesized by copolymerization of silicon monomer and acrylate monomer. Due to the trans-dimethyl structure of organic silicon, it can give the paint film surface excellent smoothness and low surface energy, which can make it difficult for graffiti contaminants to wet and adhere. Then, through the hydroxyl group on the molecular chain of acrylic resin, it can react with isocyanate or amino to cross-link and cure, and fix on the paint film surface to play a long-term graffiti prevention effect.
