Release Agents, Lubricants and Protective Coatings
Boron nitride remains lubricious and inert even at extremely high temperatures. Coatings made with BN prevent sticking to increase the life of dies/molds, improve product surface finishes, and reduce production times.

Metal Processing
In molten metal processing and metalforming applications, BN coatings protect surfaces which come into contact with hot and molten metals. BN inhibits corrosion and chemical attack and provides easier release and longer mold/die life. Applications include casting, stamping, forging, extrusion, and powder metallurgy.

Glass Making
Boron nitride’s high temperature lubricating properties make it ideal in glass making where it helps to minimize surface defects, improves mold/die life and release, and reduces clean-up time. Most glass formulations will not stick to BN.

Easy Application
Boron nitride water-based coatings are available in one and five gallon containers, and in several grades. All formulations can be applied by brushing, rolling, dipping or spraying using various commercially available methods.

Water dilution is recommended to enhance application for grades with higher solids content. Dilution is required for grade GPC, due to its thick consistency. (Please see chart below for dilution details.) Multiple coats may be necessary for complete coverage. Forced drying at 80°C for 20 minutes is recommended for each layer. BN can also be dried at ambient temperatures, although longer drying time will be required.

BN coatings can be applied to either hot or cold surfaces. Dried coatings can be readily handled, smoothed or polished with a soft, dry cloth.

In addition to the coatings described above, BN is also available in 13 oz. aerosol spray cans, shipped in 12-can cartons. Each can provides about 100 sq. ft. of coverage of high purity, extremely fine BN crystals in a fast-drying, solvent-based carrier. This product produces a smooth coating with even film build.
