Qingyuan Automotive Repair Paint Manufacturer Tells You How Many Layers of Automotive Paint Are There
A total of 4 coats of paint are applied to a typical brand new vehicle:
? Car paint layer
1. Electrophoretic paint layer: It should be mentioned here that before the electrophoretic paint layer, there is a process of phosphating the sheet metal. The first step is to form an insoluble phosphating film on the surface of the sheet metal, maintain the sheet metal, and improve its corrosion resistance. Electrophoretic paint coating is the process of soaking the entire vehicle body into the electrophoresis pool, rolling and soaking, with the primary effect of rust prevention, rust prevention, and being the bottom layer of the vehicle's rust prevention.

2. Intermediate primer layer: In fact, the electrophoretic paint layer is not directly applied to the intermediate primer layer afterwards. It is known that the entire car, which is simply corroded, must be the chassis, and it is severe. Therefore, the car chassis will be coated with another layer of anti-corrosion paint and two layers of maintenance, namely "chassis armor". After applying the primer layer, the primary filling effect is to fill in some depressions and small defects, as an isolation layer between the paint layer and the electrophoretic paint layer, which can improve the decorative properties of the paint layer. Of course, there must also be anti-corrosion effects,

3. Color paint layer: This layer displays the color of car paint, including plain paint and metallic paint (paint containing metal particles).
4. Clear paint layer: Maintain the color paint layer and increase the brightness. Strong UV resistance and weather resistance.
The above belongs to the original factory paint coating layer of sedans. Except for the color paint layer, which does not require baking, the other three paint layers require baking. People call this coating process "four coatings and three baking", and the baking temperature needs to reach 170 ℃ or above. It is rumored that some car manufacturers now choose the "three coats and two bakes" method, removing the intermediate primer layer. This car painting process will greatly protect the environment and save energy.
Car paint repair and painting usually involves these 5 layers of paint, only using different materials. They are: epoxy primer layer, atomic gray layer, (intermediate primer layer), color paint layer, and clear paint layer. Why do I need to put parentheses on the intermediate primer layer? It is because some irregular ones are replaced with red gray to save costs, and even omitted. As a result, car paint repairs are cheap but not good. A good job is not cheap.
