Description

technical field [0001] The invention relates to the technical field of metallic paints, in particular to an oily metallic paint used for surface coating of commercial vehicles. Background technique [0002] Metallic paint, also known as metallic flash paint, is a popular car finish. Fine metal powder (such as aluminum powder, copper powder, etc.) is added to its paint base. After the light hits the metal powder, it is reflected through the air film. Therefore, it looks as if the metal is shining. This metallic flash paint gives people a pleasant, light and novel feeling, and the flash degree of the metallic flash paint film can be controlled by changing the shape and size of the metal powder. The most important field of application for metallic paints is the automotive industry. The outer surface of the car sprayed with metallic paint can not only make the painted sheet metal surface look more attractive, but also change the color and even the outline of the car at differ...
