• high temperature release and lubricating agent
• for use on metals, ceramics, fibre ceramics and graphite
• produces non-wetting surfaces
• for metal melts such as aluminium and magnesium, zinc and lead
• for pressing and high pressure sintering of hard metal powders
• ready for use aerosol for an easy application
• contains "white graphite"


ALU-STOP BN-A Boron Nitride Aerosol is a special coating material based on high-purity boron nitride showing a high specific surface. This coating shows an excellent non-wetting behaviour against most metal metals and can be applied directly onto the substrate to be protected. By the use of quick-drying components the coating can be put into service after a short drying time. ALU-STOP BN-A Boron Nitride Aerosol enables an easy and quick application in research facilities as well as in the production.


• Remove dust and remains of melts etc. from the surface to be coated.
• Shake can well before use.
• Spray from a distance of 20 cm (8").
• Best results are achieved by even movements when spraying.
• Apply thin coatings. Thick coatings may may crack upon drying.
• Additional layers may be applied after drying.
