PRODUCT USES
Chemical Mastic CM-15 is formulated for use over tightly adherent rusty steel and previously painted surfaces limited to hand or power tool cleaning. Although blasting of steel is the best method of preparation, Chemical Mastic CM-15 will provide excellent adhesion and protection to non-blasted steel surfaces in any industrial facility. Specific areas include structural steel, tanks, vessels, water towers, equipment, pipe lines and racks, metal buildings, fences, catwalks, bridges, railings, fire escapes, etc., in chemical processing plants, pulp and paper mills, sewage and waste water treatment facilities, fertilizer plants, petroleum refineries, electric generating stations, coal handling operations, marine installations, etc. Chemical Mastic CM-15 can be used as a high performance primer under epoxy, polyurethane, vinyl, acrylic topcoating to upgrade corrosion resistance in severe chemical exposures.
