The full name of crystal plating is crystal coating, which belongs to one kind of coating. Because a thin layer of crystal protective film is formed on the surface of car paint after solidification, it is called crystal coating, or crystal plating for short.






At present, no matter the physical channel or the e-commerce industry, plating crystal has become a hot word in the automobile beauty circle, and is gradually defined as "coating upgrading products" by the invisible push hand of the market.






At present, there are three kinds of crystal plating, the first is polysilazane, which is the best material at present; it is often used as protective coating for military machinery, aerospace and other equipment; because of its super hard wear-resistant, weather resistant, easy to clean, stain resistant and excellent adhesion, it has been subject to the control and restriction of foreign technical barriers; until now, only one of the top foreign chemical institutions has the ability to produce in batches Therefore, there are few reports in the domestic chemical industry, but it is recognized as a long-term protective coating. The remarkable feature of this material is the smell of ammonia; due to the high density of the film, the reaction time is fast (about 1-2 minutes in summer and 2-4 minutes in winter). In addition, because of the strong adhesion and ductility of silazane, the coating is environmental and safe, except for the paint surface, plastic, rubber, chrome plating, dashboard, door panel and even leather seats can be used Many car beauty shops are the only materials that can be used as all-around crystal plating at present. However, due to the high cost of materials, low profit and technical barriers, there are relatively few businesses of this material crystal plating.






The second one is the siloxane crystal plating, which belongs to the category of organic resin (silicone resin). Because of its low cost, high profit, high technology and simplicity, most of the crystal plating adopts this kind of material, which is characterized by light smell of solvent oil. Because of the low density after film formation, the reaction time is very slow (3-5 minutes in summer, 8-10 minutes in winter). This kind of crystal plating is generally hard Low degree, poor adhesion, so the retention time is very short (generally no more than 3 months, continuous maintenance is required). In addition, the module is brittle and easy to crack and fall off, so it is only used on hard surfaces such as car paint. It should be noted that some businesses will use siloxane to fake inorganic silicon to gain the trust of car owners. It should be carefully identified, mainly based on the product smell and brightening time.






The third is inorganic silicon plating crystal, which is between the above two kinds. Generally, alcohol solvent with alcohol odor is used. This kind of plating crystal has good adhesion and good hardness after film-forming (the polishing and brightening time is similar to silazane), but its hydrophobicity is relatively poor; the general automobile beauty shop uses more.
