Boron nitride has no obvious melting point, with a maximum service temperature of up to 2800℃. Hexagonal boron nitride features a lamellar hexagonal structure, boasting advantages such as high melting point, small linear expansion coefficient, high thermal conductivity, good thermal shock resistance, high high-temperature insulation, excellent high-temperature lubricity, and strong corrosion resistance.

Boron nitride coating / release agent is an environmentally friendly product, which uses water-based or alcohol-based inorganic binders and high-purity boron nitride powder with high crystallinity as raw materials.

It has excellent lubricity and oxidation resistance, and exhibits high non-wettability with melts of non-ferrous metals (such as copper, aluminum, magnesium) and glass. This ensures that the coated surface does not react, wet, or adhere to molten non-ferrous metals/glass and their slags. It is mainly used for sealing and lubrication of automobile engines and exhaust pipes, and as a release agent in fields such as casting, stamping, forging, high-end glass products, and powder metallurgy. When applied to mold surfaces in contact with molten metals/glass, it prevents chemical corrosion of the mold, facilitates demolding, extends the service life of the mold, and greatly improves the surface finish of products.
