Aerosol spray-on insulation coating that forms a water-resistant thermal barrier on cold pipes, fittings, tanks, valves, and refrigeration components — preventing condensation, sweating, and dripping on metal surfaces exposed to cold temperatures or fluctuating humidity. Expands slightly on application to conform to irregular shapes and complex geometries where wrap-around insulation is impractical or prone to damage; dries to a hard white finish that accepts paint or primer. Seals over damaged insulation sections and acts as a reinforcing outer layer to extend service life of existing insulation. Resists surface corrosion and microbial growth caused by persistent moisture exposure. Suited for cold water pipes, AC lines, refrigeration units, valves, metal gutters, toilet tanks, and cold storage equipment. Widely used in food processing plants, industrial refrigeration facilities, shipping operations, and indoor environments such as arenas and cold lockers where moisture control directly affects equipment longevity and facility cleanliness.
