Anti-graffiti coatings are divided into sacrificial anti-graffiti coatings, semi-permanent anti-graffiti coatings and permanent anti-graffiti coatings according to their protective characteristics.
1. Sacrificial anti-graffiti coatings are usually paraffin emulsions or mixtures of paraffin and polysiloxane. When the material surface is contaminated by graffiti, the coating is removed along with the graffiti. The characteristic of this coating is that it needs to be applied again after removing graffiti each time, which increases the maintenance manpower and material resources.
2. Semi-permanent anti-graffiti coating is acrylic resin coating or epoxy, polyester resin crosslinked coating, can be repeatedly coated. It has certain corrosion resistance to the enhanced chemical cleaning agent, and can resist several chemical cleaning agent cleaning, but ultimately requires a new coating to replace it. Because the pollutants have a certain adhesion to the coating and with the increase of time, the degree of adhesion and integration into the coating will be more and more strengthened, it is necessary to use the enhanced chemical cleaning agent for cleaning.
3. Permanent anti-graffiti paint with a relatively long service life, the use of safe neutral cleaning agent or without the use of cleaning agent can be repeatedly removed on the surface of the coating of graffiti, paste or other pollutants, without losing the performance of the coating itself.
The permanent anti graffiti anti stick coating on the market according to its chemical composition, mainly divided into fluorine modified or silicon modified polyurethane, fluorine resin coating, elastic poly siloxane coating and silicone resin coating.
