Boron Nitride Coating

Processing harmony, balancing lubrication, substrate adhesion and release performance

԰ boron nitride coatings are available in several water-based formulations and an aerosol spray. After applying & drying, a dry film lubricant consisting of BN and a binder remain.

Features and Benefits

  • Lubricious
  • Non-wetting
  • Inert & chemically stable
  • High temperature stability
  • Electrical insulator
  • Low dielectric constant and loss
  • Thermal conductor

԰ produces over 50 standard and custom grades of boron nitride (BN) powders to meet a wide range of application requirements and has over 50 years of expertise in the synthesis and refinement of BN powders.

About BN Coatings

BN Aerosol Spray
BN is also available in 13 oz. aerosol spray cans that provide about 100 sq. ft. (9.3m) of coverage per can. This fast drying, solvent-based product produces a smooth coating of BN platelets with even film build.
Use Temperature
Dried BN coatings will continue to provide protection & lubrication up to 850C in oxidizing environments and up to 1800C in inert environments or vacuum.
Boron Nitride Properties
BN used for ԰ coatings are >95% pure, crystalline BN. BN has an electrical resistivity of >1x1015ohm-cm. BN has very low trace metals content and less than 0.5% soluble borates.
General Instructions for Use

Boron nitride water-based coatings are available in one and five gallon containers, and in several grades.

Water dilution is recommended to enhance application for GPC due to higher solids content. Other grades may be diluted as needed. FPD can be easily reconstituted in a container with the required amount of water using a standard paint mixer.

All formulations can be applied by brushing, rolling, dipping or spraying using various commercially available methods. Multiple coats may be necessary for complete coverage. Forced drying at 80C for 20 minutes is recommended for each layer.

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.

Potential Applications

Boron nitrides crystal structure make it an ideal lubricant, as crystals are able to slide easily between mating surfaces. BN also provides a barrier to many molten metals & glasses to prevent corrosion, surface defects & sticking.:

  • Dry film lubricant to prevent sticking to increase the life of dies/molds, improve product surface finishes, and reduce production times in casting, stamping, forging, extrusion & powder metallurgy.
  • Barrier coating for molten metal processing.
  • Die coating for injection molding to improve die release and increase production speeds.
  • Minimize surface defects, improve mold life and reduce clean-up in glass making.
  • Coating on graphite plates can virtually eliminate carbon contamination and reactivity during metallic & ceramic sintering.
  • Protect surfaces from weld spatter, provide superior stop-off protection, and protect MIG/MAG welding nozzles from weld spatter.
