Organosilicon coating has good heat resistance, high and low temperature resistance, moisture resistance, water resistance and excellent stability to ultraviolet radiation, so it is often used as heat resistant coating, electrical insulation coating and weather resistant coating.

Organic silicon has become an industry of its own. This material is used in the coating industry on the basis that the entire coating industry has been developed and people are eager to obtain more unique performance coating products. Organosilicon is mainly used in the production of coatings, including silicone resin and silicone modified resin.

Silicone resin is required for the production of high-temperature protective coatings. In the 1970s, the United States produced a lubricating coating with a temperature resistance of 600 ℃. China has also used silicone resin to design a temperature resistant coating that can withstand 500 ℃ high temperature.

The application of silicone resin is not limited to high temperature resistance, it also has the characteristics of good viscosity resistance. The coating added with silicone resin has good viscosity resistance, and the coating surface has strong dirt resistance; The resin transparency of silicone resin is used in coatings, and scratch resistant protective coatings can be prepared. This kind of coating can be applied to metal objects to maintain the natural color of metal, resist atmospheric corrosion and be easy to clean.

Modified silicone resin is also a common raw material in the production of silicone coatings. Modified silicone resin is a "modified version" of organic silicone resin. Because of its high price, poor adhesion and long curing time, it is not suitable for large-scale construction. The above shortcomings can be overcome by modifying silicone resin.

Polyester and polyacrylate modified silicone coatings are widely used silicone coatings in recent years. It has good weather resistance and stain resistance. The coating made of modified silicone resin can be used to protect the surface of mechanical parts. Especially in the automobile industry, this kind of coating is often used. The service life of the modified silicone resin is very long, and the general service age can be up to 10 years, so it is used in some long-term protection devices. Such as railway bridges, freight cars, petroleum equipment, agricultural machinery and tools.
