HSC® 1500 Coating is designed to control heat transfer on surface temperatures up to 100°C. It is water-borne, and extremely lightweight and slightly textured in appearance. HSC® 1500 Coating uses a special acrylic resin blend with specific combination of ceramic compounds added to provide a non-conductive block against heat transfer. HSC® 1500 Coating offers a "Green", non- flammable, non-toxic formula for medium heat surface applications, attics, wall cavities, crawl spaces, duct work or any interior application. The coating was designed specifically for interior insulation purposes to block the loss or gain of heat. Helps maintain negative pressures to control air flow that harms insulation efforts. HSC® 1500 Coating can be applied over metal, concrete, wood, and other substrates found in attics and wall cavities.
