Boron Nitride Coatings – Combat®


Grade Specific Properties – Various compositions are formulated using a variety of inorganic binders. As a result, variations in physical properties such as hardness, adherence, useful temperature range and ease of application are obtained.

Type A – The highest percentage concentration of boron nitride available at 39%. Extremely thick concentrate that should be diluted with water to obtain the required consistancy.

Type Sf – A general purpose coating comprised of 23% BN is a thick concentrate that is best diluted with water to the desired consistency and sprayed or brushed onto the refractory or metal mould.

Type 10Sf – Same coating properties as Sf coating. Lower viscosity than Sf coating, a ready to use formula.

Type V – A high BN composition that dries to a harder surface used in special applications where a stronger binder is needed in applications such as coating moving parts in molten metal. Excellent for coating graphite.


Combat Boron Nitride Coatings can be used up to 1372°C (2500°F) in a reducing/inert atmosphere and 850°C (1562°F) in an oxidising atmosphere, and will retain many of the properties of Boron Nitride such as:

– Non-wetting by most molten metals, salts, fluxes and slags
– Resistant to molten metal corrosion and light metal drosses
– Excellent parting plane / very lubricus
– Helps in removal of solidified metals
