Hexagonal boron nitride is considered one of the most effective materials for separating molten metal from mold and tool surfaces.

The extreme conditions in metal casting often lead to metal adhesion and reactions between the metal and the mold material, as well as surface defects and material inclusions. All too often, this results in time-consuming rework and shortens the service life of tools. But that’s all over now!

Henze BNP’s HeBoCoat and HeBoSint products are thermally stable, chemically inert, and metal-repellent—even at temperatures above 1600 °C! This enables efficient, reproducible processes in metal casting.

The unique combination of excellent temperature resistance, chemical resistance, and low wettability makes Henze BNP products the perfect choice for metal casting.

Typical applications:

• The ideal process partner for iron, precious metal, and nickel alloys, among others
• Process-critical forming components, e.g., release rings, side dams, and nozzles
• Coatings for casting tools, casting channels, or molds
• Mold and core coatings in investment casting
• Protective and barrier layers on graphite or ceramic components
