How Many Layers Does Automotive Paint Have?

[MacEmiliano]

Automotive paint consists of four layers, from the inside out: the electrocoat layer, the primer layer, the basecoat layer, and the clearcoat layer. The electrocoat layer can be roughly considered as the paint layer directly attached to the car body steel plate, also known as the primer. The primer layer is an intermediate layer between the electrocoat and the basecoat, with relatively simple functions, including UV resistance, protection of the electrocoat, improved rust resistance, and ensuring the smoothness and impact resistance of the paint surface. The basecoat layer is the colored paint layer, providing consumers with direct color perception. The clearcoat layer is the surface of the car paint, which is a transparent layer that can be directly touched with fingertips.
