Anti-graffiti paint produced in Europe and the United States. After years of development, its technology is more mature. According to its protective characteristics, it is divided into sacrificial anti-graffiti paint, semi-permanent anti-graffiti paint and permanent anti-graffiti paint.
1. Sacrificial anti-graffiti paint is usually paraffin wax. When the surface of the material is contaminated with graffiti, the paraffin is dissolved in solvent, steam or hot water, and the paraffin is removed along with the graffiti. The biggest problem with this method is the need to reapply protective paint after each graffiti removal, increasing the cost.
2. Semi-permanent anti-graffiti coating for acrylic resin coating or epoxy, polyester resin crosslinking coating, can be coated many times. It has certain corrosion resistance to the chemical cleaning agent, and can resist several chemical cleaning agent cleaning, but eventually a new coating is needed to replace it. Because the contaminants have a certain adhesion to the coating and with the increase of time, the degree of adhesion and integration into the coating will become more and more strengthened, it must be cleaned with a strengthening chemical cleaning agent.
3. Permanent anti-graffiti coating is relatively new, its coating life is long, the use of safe neutral cleaning agent can be removed many times on the surface of the coating graffiti, stickers or other pollutants, without losing the performance of the coating itself. The domestic market for permanent anti - graffiti anti - stick paint. According to its chemical composition, it is mainly divided into fluorine resin coating and silicone resin coating. The familiar inner surface of a non-stick frying pan is a synthetic resin coating coated with teoxon (PTFE). However, fluorinated resin is expensive and its application cost is high. The long chain siloxane resin of silicone coating after modification and crosslinking, its coating can be close to the antiviscosity of fluorine resin coating, and the price is much lower than fluorine resin coating.


The above permanent anti-graffiti anti-stick coating has the following common characteristics:
(1) the coating surface can be low, manifested as hydrophobic, oleophobic, graffiti or paste is difficult to carry out;
(2) Contaminants adhering to the surface are easily removed."
(3) The coating has certain anti-corrosion and anti-aging properties.
