What is the function of automobile coating?

The function of car coating on Pacific Auto Net is to keep the gloss of car paint, slow down or reduce its attenuation, and at the same time, make the paint get a protective film physically, so as to protect the paint.

The coating of automobile paint is to coat a film on the automobile paint, which aims to protect the gloss of the automobile paint from fading, and at the same time, make the paint physically get a protective film, thus achieving the purpose of protecting the paint. Macropolymers, simply speaking, are molecules linked hand in hand. Because of their strong film-forming ability, they can form a real film, so most of the automotive coating products on the market at present are macromolecular chemical products.

the principle of car paint coating is simply to coat a protective film on the car paint surface, so that the paint surface can get an invisible protective cover physically, thus achieving the purpose of protecting the paint surface. The main component of car paint is resin, and the molecular gap is relatively large. After coating, small molecular elements such as silicon, silicon dioxide and nano-inorganic silicon in the film solution can fully penetrate into the molecular gap and micropores of car paint, forming a transparent crystalline film similar to the protective film of mobile phone screen on its surface. Greatly improve the hardness and scratch resistance of the car paint surface, play a long-term sealing and protection role for the car paint, and keep the car paint as bright as new for a long time.

types

1. Although the properties and functions of fluorine coating and PTFE (Teflon) are slightly different, strictly speaking, they are both fluorine products. Fluorine products are characterized by good film forming, excellent corrosion resistance, weather resistance and wear resistance. But its biggest disadvantage is poor adhesion, and almost all substances do not adhere to Teflon coating. Because it can't be attached to the paint for a long time, its protection time becomes very short.

2. Resin coated products are widely used because of their good film forming, strong adhesion and low price, but their hardness and gloss are poor, and their oxidation resistance, corrosion resistance and weather resistance are poor, so they are gradually eliminated.

3. silicone coating products, which are also called glass fiber and glass pigment, are the latest coating products on the market. The main component of this kind of products is polysiloxane, which will form glass commonly known as Sio2 after film formation, so it is also called glassy coating. Its characteristics are: good film-forming, high hardness, high gloss, excellent weather resistance, corrosion resistance and oxidation resistance, and its adhesion is also very strong, so it is difficult to fall off once it is painted on the surface of car paint.

meaning of coating: no matter what kind of car it is, if it has dazzling colors and luster, people will envy it and chase it. Therefore, improving and protecting the luster and color of automobile paint has become the main purpose of automobile paint beauty. And 1% of the car paint will happen in the process of use:

1: Ultraviolet radiation makes the paint surface oxidized, the color darkens and the luster disappears.

2: acid rain, insect carcasses, bird droppings, glue and chemical corrosion make the paint surface form spots and the luster disappears.

3: tiny hairline marks weaken the mirror effect of the paint surface. Coating the paint with a protective film with high gloss, strong wear resistance and strong corrosion resistance will undoubtedly effectively prevent the occurrence of appeal. Therefore, high-quality automobile coating can effectively improve and protect the color and luster of automobile paint surface.
