Automobile coating is a solid continuous film obtained by one application of paint. It is a thin layer of plastic coated on metal, fabric, plastic and other substrates for protection, insulation, decoration and other purposes. The coating can be gaseous, liquid or solid, and the type and state of the coating are usually determined according to the substrate to be sprayed.

There are different names depending on the type of paint used, for example, the primer coat is called the primer coat, and the finish coat is called the finish coat. Generally, the coating obtained by coating is relatively thin, about 20~50 microns, and the thick paste coating can obtain a coating with a thickness of more than 1 mm at a time.

It is a thin layer of plastic coated on metal, fabric, plastic and other substrates for protection, insulation, decoration and other purposes.

High temperature electrical insulation coating   
The conductor made of copper, aluminum and other metals is covered with insulating paint or plastic, rubber and other insulating sheaths. However, insulating paint, plastic and rubber are afraid of high temperature. Generally, if the temperature exceeds 200 ℃, they will gather and lose their insulating properties. And many wires need to work under high temperature, what should we do? Yes, let the high-temperature electrical insulation coating help. This coating is actually a ceramic coating. In addition to maintaining the electrical insulation performance at high temperatures, it can also be closely "united" with the metal wire to achieve "seamless". You can wrap the wire seven times and eight times, and they will not separate. This coating is very dense. When you apply it, two wires with large voltage difference will collide without breakdown.

High temperature electrical insulation coatings can be divided into many types according to their chemical composition. For example, boron nitride or aluminum oxide or copper fluoride coating on the surface of graphite conductor still has good electrical insulation performance at 400 ℃. The enamel on the metal wire reaches 700 ℃, the phosphate based inorganic binder coating reaches 1000 ℃, and the plasma sprayed aluminum oxide coating reaches 1300 ℃, all of which still maintain good electrical insulation performance.

High temperature electrical insulating coatings have been widely used in electric power, motors, electrical appliances, electronics, aviation, atomic energy, space technology, etc.
