What Does Coating Mean?
1 Answers
Automobile coating refers to applying a special chemical agent onto the car's paint surface. This agent undergoes a chemical reaction on the paint surface, forming a thin, hard, and transparent protective film. This film protects the car paint from external dirt, impurities, etc., for a certain period, ultimately preventing oxidation, making it easier to clean, and maintaining the paint's shine. Car paint is frequently exposed to sunlight and complex air environments, forming a visible oxidation layer within 60 days. The formation of this oxidation layer leads to fading and surface roughness of the car paint. Although new cars generally have a protective layer, over time (usually around 3 months), the glossy oil on this layer thins and peels off, losing its protective effect. Therefore, within a few months of owning a new car, without paint protection, strong ultraviolet rays, acid rain, and dust can easily damage the paint. Thus, it is highly advisable to use coating as a protective measure for the car paint after purchasing a new car. Methods to Check Coating Products: 1. Look: Determine if it is a water-soluble series product. Genuine coating products consist of a series of three products, including "bonding agent," "base film," and "protective film," each clearly labeled. Additionally, when poured out, the product should be water-like, whereas fake coatings usually come as a single product, either paste-like or emulsion-like. 2. Smell: Check for any irritating odor. Pour a small amount of the product onto your palm and rub your hands together until they warm up. Genuine coating products have no odor, while fake ones emit a strong fragrance or other irritating smells. 3. Test: The ability to fully dissolve in water is a standard to identify if it is inorganic. Use a test tube or a glass of water for the test, adding a drop of the coating product. Genuine coating products will fully dissolve when shaken, as they are composed of inorganic substances like fluorine, silicon, cellulose, and glass. Fake coating products, however, will form a milky, cloudy liquid or clump, as they contain oily components that are insoluble in water.
