The application of liquid polymers or plastic to the surface of a workpiece by dipping or immersion is known as a plastic coating. The outcome is a thick plastic finish that may be used for both protection and decoration. This increases the material’s resistance to scratches, wear, corrosion, and the weather.
A plastic coating offers metals a thick, wear-resistant finish that resists corrosion by keeping water and air away from the metal’s surface. The work is heated before being dipped into a tank containing powdered polymers rendered fluid by compressed air passing through porous tiles or, in the case of PVC, a plastisol paste.
