| BORON NITRIDE COATING Type RS-BNCoat |
GENERAL INFORMATION
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).

USE NOTES
Paint:
Resuspend if needed. Clean surfaces to be painted of oils dirt, scale
etc. Apply one thin layer by brush or spray like ordinary house paint.
Allow to dry at room temperature before use.
Aerosol Spray: Surfaces to be sprayed should be cleaned and degreased first. Shake can well before using. Hold can 150 to 300 mm (6 to 12 inches) from surface. Apply a thin, uniform coating, using even movements. Respray as needed. Use in a well-ventilated area. Acetone/Alcohol Based.
