Zircon powder coating is primarily composed of zircon powder, featuring high melting point, oxidation resistance, excellent thermal stability, low thermal expansion coefficient, minimal high-temperature volatilization, and superior fatigue resistance. The coating forms a unique three-dimensional network crystalline structure, exhibiting high-temperature resistance, non-volatility, good ductility, and high film-forming capability. It can remain stable for extended periods at high temperatures up to 1280°C without aging and maintains strong adhesion. This product can be used as a surface oxidation protection coating during heat treatment of steel.
