Boron Nitride Coating
Non-wetting BN coating for ladles, troughs, thermocouples and molds
Overview
What it is and where it works
Water-based boron nitride coating that creates a non-wetting, lubricating surface on tools and refractories in contact with molten aluminium, magnesium and zinc. It is painted or sprayed in thin coats on ladles, launders, thermocouple tubes, dies and ingot molds to stop metal from sticking and to protect the surface. We source ready-to-use or concentrate grades.

Frequently Asked Questions
Why does my coating flake off?
Thick coats crack in use. Apply thin layers on a clean, warm surface and let each layer dry before the next.
Can it go on wet before pouring?
No. The coating must be fully dry before it contacts molten metal.
