Hexagonal boron nitride as a non-stick solution
Challenge
Adhesions occur when metallic, glassy, or ceramic surfaces are exposed to high temperatures, pressure, or melting phases. This intensifies surface-energy interactions, leading to localized melting, diffusion, microdamage, and unstable boundary layer conditions.
Consequence
The adhesive interactions that occur in this process lead to material transfer, surface damage, and unstable process conditions. This results in increased scrap, tool wear, and maintenance costs, while process stability decreases. As thermal and mechanical stress increases, the tendency for adhesion intensifies significantly and becomes a critical factor for cost-effectiveness and component quality.
THE HENZE SOLUTION
Hexagonal boron nitride possesses exceptional non-wetting properties that form a stable, anti-adhesive surface even at extreme temperatures of up to 2,200°C. Its layered structure, low surface energy, and chemical inertness toward molten metals and glass effectively prevent material adhesion and ensure low-friction processes. The result is significantly reduced adhesion, leading to greater process reliability, higher component quality, and noticeably improved cost-effectiveness.

Frequently Asked Questions
Why do unwanted deposits often form in industrial processes?
Whenever high temperatures, pressure, or molten materials come into contact with tools and components during the processing of metals, glass, or ceramic materials, unwanted deposits frequently form. These can disrupt the process, cause tool wear, and result in extremely labor-intensive cleaning tasks.
How do boron nitride products from Henze BNP prevent materials from sticking?
Boron nitride is a true all-rounder and has an excellent release and lubricating effect by nature. The use of sintered HeBoSint® components, HeBoFill® powders or liquid HeBoCoat® coatings creates an extremely temperature-resistant non-stick effect on the surfaces. This layer is chemically inert and reliably prevents process media or hot metal splashes from sticking to the components.
In which specific applications is the non-stick and release effect of boron nitride particularly in demand?
- Sintering technology: HeBoSint® substrates and HeBoCoat® coatings reliably prevent the sintered material from sticking to the substrate.
- Welding, soldering, and laser processing: These coatings protect welding nozzles, soldering tips, and workpieces from unwanted adhesion of welding spatter, solder spatter, and metal spatter. In laser processing, they also reduce burr formation, as molten residue can flow away more easily.
- Metal Casting & PVD Systems: HeBoCoat® provides the necessary release effect for channel materials in casting and makes cleaning easier. The non-stick effect also makes it significantly easier to clean metal shielding frames in PVD and plasma systems, saving valuable process time.
