High-Temperature Lubrication and Mold Release
Improving the operating life and performance consistency of metal, plastic and refractory parts at high temperatures is challenge faced by many industries. Combat® Boron Nitride powders and aqueous coatings offer a solution for this challenge.
By leveraging boron nitride’s thermal and chemical stability in combination with its ability to reduce friction and wear, Saint-Gobain is able to customize the properties of Boron nitride to best meet the unique needs of a wide range of industries.
Refractory Coating for Non-Ferrous Alloys
Utilization of a Saint-Gobain boron nitride protective coating on refractory surface in contact with non-ferrous molten metals such as aluminum, copper or zinc dramatically extends the life of the refractory system and the efficiency of the metal processing line. Saint-Gobain SF coatings, with an alumina binder system, provide a high-grade protection layer that has strong adhesion, wear resistance and is non-wetted by molten metals in demanding environments.
The contact angle of a molten metal on a surface is a measure of the protection offered by that material. The higher the angle, the better the protection from infiltration and corrosion. With a high contact angle even at elevated temperatures, Boron Nitride shows excellent resistance to molten aluminum.
High Performance Friction Materials
Boron Nitride fillers are commonly used in high-performance friction materials such as brake fluids for aviation and racing industries or cutting oils for machinery operating at high temperatures.
In applications that require rapid heat dissipation, Boron Nitride offers a much superior solution than Graphite or MOS2 due to a combination of better thermal conductivity, high oxidation resistance, chemical inertness and low coefficient of friction. Whether used as a solid surface lubricant or as a finely dispersed, micron-sized filler particles in fluids, Boron Nitride delivers the benefits of improved lubrication and heat withdrawal in a variety of dynamic friction applications.
Combat® Boron Nitride powders for break fluids and NSF certified Idealube® Boron Nitride powders for incidental food contact, offer solutions to high-temperature industrial lubrication applications.
