- Customizable BN concentration (5–20%)
- Non-staining, graphite-free
5. h‑BN Suspensions & Pastes (Water, Oil, Solvent-Based)
Stable, ready-to-use suspensions and pastes of BN for precision coating applications. Designed for brush, dip, or spray, depending on the process.
- Aqueous, solvent, and oil-based systems
- BN concentration up to 25%
6. h‑BN Wax Candles
Solid wax sticks infused with h‑BN powder, used for quick and clean application of BN to hot dies, molds, or extrusion tools.
- Leaves behind a thin, white BN layer
- No smoke, no carbon residue
- Suitable for maintenance of coated tooling

The Hexagonal Boron Nitride spray is a high-temperature anti-stick release agent and lubricant. When it is required to apply a thin film of Hexagonal Boron Nitride coating on a surface or any other hard-to-reach places the spray is convenient to use. The spray is available in 500ml/ 300 gms cans.
Properties of Hexagonal Boron Nitride Aerosol spray
- The spray has excellent lubricating properties.
- It bonds well with the substrates and forms a coating film.
- It has properties like good chemical inertness and an electrical insulator.
- It is a good thermal conductor and this results in better heat dissipation.
- It shows stability at high temperatures – 1000° C in air, 1400° C in a vacuum and 1800° C in inert gas.
- Some of its properties are low thermal expansion, low dielectric constant and non-wetting.
- It does not contain any fluorocarbons or leads and is not harmful to the ozone.
Water based Hexagonal Boron Nitride Suspension is used for several lubrication applications :
a. It can be diluted with water and applied on any surface via spraying, brushing or swabbing
b. it provided excellent non-wetting properties to molten metal such as Aluminium, Zinc etc
c. it provides excellent release & anti-stick properties at high temperatures
We can make HBN Suspensions upto 40% solid in paste form.
