Zircar Refractory Composites RS-BN Coat BORON NITRIDE COATING

ZRCI Boron Nitride Coating Type RS-BNCoat is a high temperature, anti-stick release agent/lubricant for glass forming, hot pressing, super-plastic forming of alloys and melting/casting of non-ferrous metals. Type RS-BNCoat forms a non-wetting, non-reacting layer with molten aluminum and magnesium and their dross. It is ideal for forming a barrier layer to protect metal, ceramic, or graphite substrates used for metal transport or casting operations. Type RS-BNCoat’s high electrical resistance and high thermal conductivity makes it useful as a protective coating on electrical heating elements. It is available in a paint or as an aerosol. The aerosol allows easy application of uniform, thin layers, and the acetone/alcohol based carrier assures fast drying. Type RS-BNCoat is useful to temperatures to 1816°C (3300°F) in inert and reducing atmospheres. In vacuum atmospheres, RS-BNCoat can be used to 1400°C (2552°F) before sublimation, and in oxidizing atmospheres, its use temperature is 1093°C (2000°F).Information provided by ZIRCAR Refractory Composites, Inc.
