AdTech Boron Nitride Coating is a high-performance protective coating designed for aluminum casting equipment. It effectively reduces molten aluminum adhesion, minimizes oxidation, and prolongs refractory and metallic component life. BN coating is widely applied to launders, filter boxes, hot tops, and casting tips, offering superior lubrication, chemical inertness, and thermal stability.
Boron Nitride Coating Advantages
- High temperature stability, and non-stick aluminum.
- It can be applied to hot or cold surfaces. After drying the coating, treat it with a dry soft cotton cloth.
- Special formula, water base, easy to use.
- Environmentally friendly paint, non-toxic and non-polluting.
- The coating has a strong binding force with the substrate. The coating has high hardness, anti-friction and impact resistance.
Why Choose Boron Nitride Coating for Aluminum Casting?
Boron Nitride Coating is engineered to address the challenges of modern aluminum foundries:
- Non-Wetting to Molten Aluminum: Prevents sticking and reduces dross formation.
- Thermal Stability: Operates reliably at temperatures up to 1000°C.
- Chemical Inertness: Resists reaction with molten aluminum, maintaining metal purity.
- Lubrication: Improves metal flow and reduces turbulence.
- Maintenance Reduction: Extends refractory service life and reduces cleaning intervals.

Instructions of BN Coating
This product needs to dilute before use. Different painting objects require different dilution ratios. After dilution, mix well and apply with a brush (or spray). After coating, bake at a temperature of about 300 ℃ and use it after the coating has dried. BN coating has excellent lubricity and oxidation resistance under a high-temperature environment, and boron nitride has its unique physical and chemical properties. Even at extremely high temperatures, it still protects its unique lubricity, non-stick property, anti-seize and anti-corrosion oxidation of metal or graphite. In addition to being used for the protection of various refractory materials, it also has excellent protection against chemical corrosion and anti-sticking.
Note: Before painting, clean the surface of the material, the coating should be uniform. Do not make BN gather on the surface, that is, do not apply too thick.
FAQ
1. Can Boron Nitride Coating be used with ceramic filters?
Yes, fully compatible.
2. Does it improve metal cleanliness?
Yes, significantly reduces contamination and dross.
3. Is BN Coating safe for aluminum alloys?
Yes, high-purity boron nitride is chemically inert.
