BLACK VELVET, FACTORY MANIFOLD GRAY, and POR-20 BRILLIANT ALUMINUM are Very High Heat-Resistant Coatings designed for use on steel subject to elevated temperatures. FACTORY MANIFOLD GRAY and POR-20 will withstand temperatures on a continuing basis up to 1400°F, while BLACK VELVET will will withstand temperatures on a continuing basis up to 1200°F. When subjected to high heat concentrations, FACTORY MANIFOLD GRAY will darken in color (as will cast-iron). Though they will dry to the touch in about four(4) hours and may be handled, these coatings will not arrive at full cure until they have been exposed to heat concentrations of at least 300 degrees Fahrenheit.

Metal Preparation: Surfaces to be coated must be clean, dry, and free from oil, grease, and any other coating which cannot resist high temperatures (paints, varnishes, lacquers, metal prep coatings, etc). Sandblasted surfaces are ideal, as are wire-brushed or sanded or filed surfaces. Surgical-type gloves should be worn for handling to keep natural body oils off the prepared surface.
