At present, the high temperature resistant coatings on the market can be mainly divided into organic high temperature resistant coatings and inorganic high temperature resistant coatings.

Inorganic high temperature resistant coating has high hardness, and its heat resistance can reach 400~1000 ℃ or even higher. However, the paint film is brittle, and its water resistance is poor before it is fully cured. The requirements for substrate surface treatment are strict.

Organic high temperature resistant coatings include heterocyclic polymer coatings (polyimide, polyamide, imide, polyphenylene sulfide and polyethersulfone) and elemental organic polymer coatings (organic silicon, organic fluorine and organic titanium). Among them, heterocyclic high-temperature resistant coatings have been used for many years at home and abroad, mainly for high-temperature insulation, with high price, poor storage and strict requirements for pigments; Although the high temperature anti-corrosion performance of the organic fluorine coating is superior, it is not easy to dissolve in the solvent. Even if it is dissolved, its solid content is low, the film formation is thin, the construction is inconvenient, and the mechanical performance of the organic fluorine coating is not ideal.
