Generally, car paint surfaces will have at least 4 layers of paint, which are multi-layer paint, primer, top paint and color paint. Their previous roles are also quite different, and the colors of top paint and color paint are usually acceptable. Intuitively, the color of the primer will only be revealed after it is scratched, so many friends are very curious, what color is the general car primer?
The car primer is the first layer of paint on the car body. Generally, the next spraying process can only be carried out after the primer is sprayed. As a primer, it must first protect the car body. The primer directly contacts the car body. The car body is mainly composed of metal, which requires that the primer should have good anti-corrosion and anti-rust properties, and also have good adhesion, including adhesion to the car body and top paint.
Now primers can generally be divided into dip primer, water-based dip primer, anodic electrophoretic primer and cathodic electrophoretic primer. Generally, cars use cathodic electrophoretic primer, and the color of general primer is white or gray. Choose colors according to different models. For example, a black car will use a white primer, while a white car will choose a gray primer, mainly to make it easier to identify the primer when the paint is scratched.
The car is scratched, no matter if the primer is in or out, as long as there is a deep scratch, it is recommended to repair it, to avoid old rust and more affect the appearance. After the metal shell is scratched, the primer will not rust, but if the metal is exposed, even a small amount must be repaired in time. Otherwise, the area may increase.
