Aerol Boron Nitride Spray | High Temp Lubricant, Release Agent & Coating (800°C Air / 1950°C Inert) | Dry Film for Hot Surfaces & Tools | 300g/411ml – Grade 7720

High Temperature Lubrication: Boron nitride remains effective up to 800°C in air and 1950°C in inert gas, providing excellent dry lubrication for hot parts and tools.. Dual Property Material: Boron nitride (BN) acts as an electrical insulator at room temperature and becomes a semiconductor at high temperatures.. Protective Coating: Provides a stable coating for metals, ceramics, ceramic fibres and graphite, remaining inert to molten metals, glass, and salts.. Wide Application Range: Ideal for thermocouple and probe protection, casting tools, foundry moulds, gasket wire drawing, electrical insulation, sintering, and as a release agent in metallurgy and plastic injection moulds.. Easy Spray Application: Clean the surface, shake the aerosol well, spray from about 70 cm, and apply several thin, even layer allowing each to dry before the next for best coating performance.
