Coatings For Protection, Insulation, Decoration

Coating is a solid continuous film obtained by one application of paint. It is a thin plastic layer coated on metal, fabric, plastic and other substrates for protection, insulation, decoration and other purposes. The coating can be in gaseous, liquid or solid state, 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 coating used, such as the coating of the primer is called the primer layer, and the coating of the topcoat is called the topcoat layer. Generally, the coating obtained by the coating is relatively thin, about 20~50 microns, and the thick-build coating can obtain a coating with a thickness of more than 1 mm at a time.

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

High temperature electrical insulating coating

The outside of the wire made of copper, aluminum and other metals may have insulating paint, or insulating coverings such as plastic and rubber. However, insulating paints, plastics, and rubbers are all afraid of high temperatures. Generally, if the temperature exceeds 200 °C, they will aggregate and lose their insulating properties. And many wires are required to work at high temperatures, so what to do? Yes, let the high temperature electrical insulation coating help, this coating is actually a ceramic coating, which in addition to maintaining electrical insulation properties at high temperatures In addition, it can be closely "united" with the metal wires to achieve "seamless", no matter how you bend the wires, they will not be separated. This coating is very dense, and the difference between the two voltages Very large wires touch together, and no breakdown will occur.

High-temperature electrical insulating coatings can be divided into many categories according to their chemical composition. For example, boron nitride or aluminum oxide and copper fluoride coatings on the surface of graphite conductors still have good electrical insulation properties up to 400°C. The enamel on the metal wire is up to 700°C, the phosphate-based inorganic binder coating is up to 1000°C, and the plasma sprayed alumina coating is up to 1300°C, all of which still maintain good electrical insulating properties.

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