CeraGlide™ Boron Nitride Industrial Coatings
CeraGlide™ Boron Nitride (BN) coatings are composed of a high purity BN powder base paired with a high-temperature bond phase. Supplied in a liquid form suitable for brushing, they can be diluted with water to spraying and dipping consistencies and applied to a variety of porous and non-porous materials including ceramics, metals, graphite and glass.
Resistant to and non-wet by most molten metals, slags and drosses, CeraGlide BN coatings can be used up to 1372°C (2500°F) in a reducing atmosphere and up to 850°C (1562°F) in an oxidizing atmosphere, and retain many of its properties such as high temperature lubricity and corrosion resistance.
- Non-wet by most molten metals, salts, fluxes and slags
- Resistant to molten metal corrosion and light metal drosses
- Excellent parting plane and lubricity for high temperature release
- Helps in removal of solidified metals
New Improved Grades SF+ and 10SF+
Suspension stability and effective solids dispersion are important for coating consistency and performance. A precisely engineered and high purity BN powder, a nearly neutral pH and a premium alumina binder makes for a new and robust base for CeraGlide boron nitride coating grades SF+ and 10SF+. The improved binder dispersion offers more consistent and even coating layers for better adhesion and performance. The resulting solids stability reduces settling and allows for easy mixing and tighter viscosity ranges of the coating.
With these improvements, CeraGlide BN coatings not only offer excellent performance in a broad range of demanding applications on ceramic and metal substrates, but also a better fit for automated and robotic applications or when there is extended time between uses.
CeraGlide™ BN Coatings, Type SF+
A general-purpose thick coating offers premium value and flexibility of concentrated BN in aqueous phase that can be used as is, or diluted with water to desired thickness and viscosity.
CeraGlide™ BN Coatings, Type 10SF+
A ready-to-use formulation for spraying, brushing or dipping, 10SF+ combines simplified set-up, efficiency and performance in automated and robotic applications, eliminating possible variation caused by dilution on site.
CeraGlide™ BN Coatings, Type A
A high-viscosity paste with a unique aluminum phosphate binder and higher solids content for custom dilution. Offers a very strong bond with many different refractories and glass substrates.
CeraGlide™ BN Coatings, Type V
A thick composition with a magnesium silicate binder that dries to a harder coating, particularly useful in applications requiring additional durability such as moving parts in molten metal. Excellent for coating graphite.

Coatings FAQs
The main difference is the type of binder, but there are also various levels of BN content, pH and total solids content. The datasheet lists our commercially available grades as well as their differences.
Grade SF+ is concentrated, thick coating with yogurt-like consistency. This material must be diluted before being applied by spraying and many of our customers routinely dilute it before they apply by brushing. Type 10SF+, on the other hand, is a ready-to-apply, thinner formulation that eliminates the messiness of diluting on site.
Type SF+ and 10SF+ can operate at the highest temperature (over 1500°C) in N2 or inert environments. BN in all of our coatings starts to oxidize in air at around 900°C.
Yes, our CeraGlide Best Practices bulletin outlines recommendations for applying our coatings in detail. Whether spraying, brushing, or dipping, it is common practice to conduct trials with your specific substrate and application method to find the best conditions. Preheating the substrate to 100-200°F can help improve adhesion and reduce drying times for all coating grades. Once the coating is dry and has reached the desired thickness (we recommend building up layers with approx. 0.001" thickness), the coating is ready to use - no bake-out is required.
Shelf life for BN coatings is 1 year for an unopened container. The coatings should be stored in a tightly sealed container at room temperature.
