Boron Nitride Coatings

Key Services & Products

Boron Nitride Coatings are entirely inorganic, composed of boron nitride powder and a high temperature bond phase. Supplied in a liquid form suitable for brushing, Boron Nitride Coatings can be diluted with water to spraying and dipping consistencies and applied to a variety of porous and non-porous materials including graphite, metals, ceramics and organics.

Applications

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

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

Specific Grade 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 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 mold.

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

Type 5Sf - Same coating properties as 10Sf but even lower viscosity.

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.
