Is the car's primer white or black?
1 Answers
The car's primer can be either white or black, depending on the specific model and color choice. For example, black cars typically use white primer, while white cars often use gray primer. This is mainly to make it easier to identify the primer when the paint is scratched. Currently, primers can generally be categorized into dip primers, water-based dip primers, anodic electrophoretic primers, and cathodic electrophoretic primers. Most passenger cars use cathodic electrophoretic primers. The car primer is the first layer of paint applied to the body. Generally, only after the primer is sprayed can the next painting process proceed. As a primer, its primary function is to protect the car body. The primer comes into direct contact with the body, which is mainly made of metal. Therefore, the primer must have excellent anti-corrosion and anti-rust properties, as well as good adhesion, both to the car body and the topcoat.
