Boron Nitride Coating

Pyro-Paint™ 634-BN is a single-part, odorless, water-dispersible, boron-nitride-filled, high-temperature coating formulated to resist molten metals, glasses and salts in applications up to 1560°F. It is particularly effective in resisting nonferrous metals such as molten aluminum and magnesium. Pyro-Paint 634-BN is most frequently applied to metal and refractory foundry structures such as crucibles, ladles and troughs. It provides a highly lubricious and chemically and erosion-resistant interface between a molten material and the underlying metal or refractory structure, resulting in increased system life. Pyro-Paint 634-BN is a simple to use, environmentally friendly, water-based formulation containing no volatile organic compounds.
