What is the normal thickness value of car paint?
2 Answers
According to relevant regulations, the minimum paint thickness for vehicles with a base price below 50,000 yuan should not be less than 90um, while for vehicles priced above 50,000 yuan, the minimum paint thickness should not be less than 120um. Generally, the thickness of car paint ranges between 120 to 180 micrometers, with a Mohs hardness between 0.4 and 0.6. Below is the relevant introduction: 1. Definition of car paint: Car paint refers to the paint sprayed on the car body, which consists of four layers. The outermost layer is the clear coat, followed by the topcoat, then the primer, and finally the electrophoretic coating. 2. Function of car paint: Applying paint to the car body forms a protective layer on the surface, making it less susceptible to corrosion, extending the vehicle's lifespan, and enhancing its aesthetic appeal. Typically, manufacturers preset various body colors before the car leaves the factory, and these colors are determined by the paint applied to the body. If you are not satisfied with the purchased car's color, you can apply to modify the car body color within legal limits after approval.
As a car owner who frequently pays attention to new car details, I believe the normal paint thickness generally falls between 100 to 150 microns—about the thickness of a sheet of paper. New cars typically fall within this range when leaving the factory. For example, Japanese cars might be slightly thinner at 80-120 microns, while German cars tend to be thicker at 120-180 microns. To check, it's best to use a simple paint thickness gauge, which many car washes can lend you. Paint that's too thin is prone to issues like rust or fading under prolonged exposure to sunlight or rain erosion; paint that's too thick might indicate a respray, which could affect resale value in the used car market. Remember to wax regularly to maintain the paint's shine, as it slows aging and avoids frequent washing scratches. In short, don't fixate too much on the numbers—focus on whether the overall paint health is smooth and free of bubbles.
