DBN Drache Boron Nitride

DBN was developed by Drache and is produced in-house at Drache’s own manufacturing facility. It is a coating primarily used for aluminium casthouse applications.

The coating is manufactured on modern equipment assuring an excellent and consistent quality. It is available in three different types, which differ in their boron nitride content.

DBN – Drache Boron Nitride key facts

The coating can be used either directly or needs to be diluted prior to use, depending on the type.

Special characteristics

Non-wettability: Excellent non-wettability and chemical resistance to all aluminium alloys
Efficient separation: Even very thin DBN coating layers with a thickness of 100 microns only give excellent efficiency
Different types: Available as DBN 25 i, DBN 15 i and DBN 10 i RTU
Colouring: Each type can be provided in three different colours upon request. Only organic, non-toxic coloring agents are used.
