Boron Nitride Coating suits applications up to 1,560°F.
Press Release Summary:
Consisting of single-part, odorless, water-dispersible formula, Pyro-Paint(TM) 634-BN protects metal and refractory surfaces from corrosion by molten glass, metals, plastics, and salts in applications to 1,560°F. Non-wetting, VOC-free product is formulated with solids content of 38.6% by weight, resulting in dry film greater than 95% boron nitride with coverage rate of 345 ft²/gal, assuming 1 mil thickness. Coating dries at room temperature in 1-2 hr and cures fully in 1-2 hr at 200°F.
Original Press Release:
Pyro-Paint 634-BN Hi-Temp Boron Nitride Coating Now Available
SUMMARY
Pyro-Paint(TM) 634-BN, a new high temperature, non-wetting, boron nitride filled coating
developed by Aremco Products, Inc., is now used to protect metal and refractory surfaces from corrosion by molten glasses, metals, plastics and salts in applications to 1560°F (850°C).
FEATURES
Pyro-Paint(TM) 634-BN is a single part, odorless, water-dispersible, boron nitride filled, high temperature coating, formulated to resist molten metals, glasses, plastics and salts in applications to 1560 oF (850 ºC). It is particularly effective in resisting non-ferrous metals such as molten aluminum and magnesium.
Pyro-Paint(TM) 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(TM) 634-BN is a simple to use, environmentally friendly, water-based formulation
containing no volatile organic compounds. It is formulated with a solids content of 38.6% by weight, resulting in a dry film of greater than 95% boron nitride and a coverage rate of 345 ft2/gal assuming a 1mil dry film thickness. It is easy to apply with a brush, roller or conventional spray equipment; it dries at room temperature in 1-2 hours and cures fully in 1-2 hours at 200°F.
Cleanup of uncured material is accomplished easily with warm water and soap.
Pyro-Paint(TM) 634-BN is part of a line of refractory coatings based on ceramic fillers including alumino-silicate, carbon, graphite, silicon carbide, yttrium oxide, and zirconium oxide.
