What is the function of car paint?

Car paint serves to protect the vehicle from various corrosive elements in the atmosphere, decorate the car, indicate the type of vehicle, improve comfort and sealing, and prevent noise caused by vibration. Below are the principles and composition of car paint: Principles of car paint: The main component of car paint is resin, which has relatively large molecular gaps. After coating, small molecular elements such as silicon, silicon dioxide, and nano-inorganic silicon in the coating solution can fully penetrate into the molecular gaps and micropores of the car paint, forming a transparent crystalline layer on its surface similar to a smartphone screen protector. This significantly enhances the hardness and scratch resistance of the car paint surface, providing long-term sealing protection and keeping the car paint bright and new for a long time. Composition of car paint: The car paint surface consists of four layers, from the inside out: the electrophoretic layer, the middle coat layer, the color paint layer, and the clear coat layer. After the entire body is assembled, it is immersed in an electrophoretic tank, forming an electrophoretic layer on the surface of the body.
Car paint isn't just about looking good. The exterior paint layer acts like armor for the vehicle, protecting it from wind, sun, and rain. Without it, exposed metal bodywork would quickly rust when exposed to moisture. Quality paint creates a barrier against acid rain, bird droppings, and road contaminants. It also provides UV protection - without this layer, plastic components would rapidly deteriorate and colors would fade under prolonged sun exposure. The glossy paint surface helps rainwater slide off easily, keeping the car cleaner and reducing washing frequency. I've seen many older cars with severely worn paint, covered in rust spots that significantly reduce resale value.
