What are the commonly used high temperature resistant coatings?

At present, there are two kinds of high temperature resistant coatings: silicone and inorganic silicon. =

1, silicone high temperature resistant paint (continuous high temperature resistance of 200- 1200℃)

Widely used in non-metallic and metal surfaces such as blast furnace, internal and external walls of hot blast stove, chimney, flue, drying channel, exhaust pipe, high-temperature hot gas pipeline, heating furnace and heat exchanger.

2. Inorganic silicon high temperature resistant coating

Inorganic silicon high temperature resistant paint, also known as zinc silicate primer, is an inorganic zinc-rich primer, which can continuously resist high temperatures below 400 degrees and has excellent chemical corrosion resistance. It can be divided into water-based high-temperature resistant paint and alcohol-soluble high-temperature resistant paint.

Painting function

Anti-corrosion, waterproof, oil-proof, light-resistant, temperature-resistant, etc. Objects exposed to the atmosphere are corroded by oxygen and moisture, resulting in metal corrosion, wood decay, cement weathering and other destructive phenomena.

Coating a protective film on the surface of an object can prevent or delay the occurrence and development of these damage phenomena and prolong the service life of various materials. Therefore, protection is a major function of coatings.

When objects made of different materials are coated with paints, they can get rich and colorful appearances, beautify the living environment of human beings and make a significant contribution to human material and spiritual life.
