The flatness of the paint film on the surface of the roller coated board should be higher than that of the spray coated board. The color is divided into pearlescent and matte, and the most common ones on the market are pearlescent. Its price is higher than spray painting. The biggest feature of roller coated board is its extremely high color simulation; The quality and grade of the roller coating process vary greatly, not only related to all materials, but also to how many times it is colored. For example, two coats and two rolls, which means spraying and baking once, and then spraying and baking again, make the color more uniform and smooth. Good roller coating boards are also expensive, with realistic colors and strong durability.
Imported fluorocarbon roller coating is also a type of roller coating, which adds fluorocarbon to the pigment, making the color adhesion stronger, service life longer, acid, alkali, and corrosion resistant. It is often used in the external decoration of buildings (not afraid of wind, rain, and rain), and the price cost is very high, making it the highest grade of roller coating boards.
