BN-Hardcoat® is non-wetting with molten aluminum, magnesium, zinc and other non-ferrous metals and their drosses. Ideal for high-wear uses where all other boron nitride coatings fail. BN Hardcoat should ONLY be applied and dried at room temperature.

NOTE: This paint contains acrylic polymers. Do not use elevated temperatures for the drying process. Dry at room temperature before placing into a furnace environment where any emitted vapors or volatiles will be combusted.
