Boron Nitride occupies a unique place among materials because of its unusual physical, thermal and dielectric properties. It has a hexagonal crystalline structure resembling that of graphite, and is available in solid, powder, coating or aerosol form.
Boron Nitride aerosol spray consists of boron nitride powder dispersed in an acetone carrier and carefully compounded with a small amount of binder to facilitate adherence. A propellant that is ozone-friendly and non-carcinogenic drives the spray. However, this propellant is flammable and should be kept from open flame, sparks, heat or other ignition sources.
Boron Nitride aerosol is a very lubricious drying spray which deposits a thin film (.0005″) boron nitride powder on sprayed surfaces. This powder film is very lubricious, produces an excellent anti-stick surface and will also act as an oxidation up to 850’C. It is chemically inert to most organic and corrosive agents, and is not wet by molten glasses or slags.
Boron Nitride aerosol may be used as a coating for:
- High temperature release (crucibles, molds, transition plates)
- High temperature lubrication
- Corrosion resistance to molten metals, molten glasses and slags
- Anti-oxidation barriers
- Anti-stick barriers during hot pressing operations
Method of Application
Surfaces to be sprayed should be clean and free of dust and organics. Roughing the surface with a fine grit sandpaper can help facilitate a mechanical bond. Shake the can well before using. Hold the can approximately 18″ away from the surface to be coated and spray with a uniform sweeping motion. Do not spray into open flame. The approximate coverage of one 12 oz. can of aerosol is 75 sq. ft. As with all aerosol sprays, be sure to use appropriate safety precautions as outlined in the material safety data sheet.
Boron Nitride Aerosol Sprays are available in 400ml cans or by the case (12 cans per case).
