Automobile paint is composed of three parts: primer, intermediate coat and top coat. There are two types of car top paints, namely natural paint (commonly known as plain paint) and metallic glitter paint (commonly known as metallic paint), roughly half of them. In recent years, the metal paint series has developed rapidly, and the color has also developed in the direction of high transparency, depth and high color. From the color point of view, under normal circumstances, milky white or fruit colors are ordinary paints, while black, silver and other colors are mixed with metal substances, the color is brighter and the adhesion is stronger. But now Audi and Mercedes-Benz use nano-technology paint, and the barrier between paint molecules is smaller, so the effect is better. Automotive topcoats are mostly composed of film-forming substances (resins), pigments (including extender pigments), solvents and additives.
Pigment is the material of the top paint color, which does not volatilize. It gives the paint the hiding power; the film-forming material is the material that determines the type of paint, generally composed of natural resin or artificial resin, and its function is to keep the pigment bright and make it It is strong and durable and can adhere to the surface of the car body; the solvent is an easily volatile component in the paint, its main function is to fully dissolve the resin in the paint film, so that the paint can be applied normally; the proportion of additives in the paint generally does not exceed 5% , Plays the role of accelerating drying and enhancing gloss, and can improve the chemical resistance of car paint.
Snow also has a great impact on the paint surface. Snow contains a lot of corrosive substances such as acid, alkali or salt. If the snow covering the car is not removed in time, the car paint will be corroded by the corrosive components in the snow. , Over time, it may rust the car paint, make the exterior bright glaze lose its luster, and cause the car paint to peel off in severe cases. Therefore, it is best for car owners to wash the car immediately after snow, even if the weather forecast shows that it will snow in the next few days, do not drag the car without washing it. Washing the car immediately after snow will protect the car.
