KEY FEATURES Premium aluminum foil with high tensile strength. Aggressive epoxy resin coating with pressure sensitive, extreme weather oily adhesive provides great performance in a broad temperature range from -20℃ to 120℃. Excellent for both hot and cold ducts due to its super thermally conductivity and vapor shielding. Make sure the surface you're applying aluminum foil tape to is free of grease or other debris. Great applications in general repair such as duct insulation, sealing metal (aluminum, copper, steel) and plastic seams / joints, or on metal surfaces, for Metal Pipes, Air Vents, Furnace and AC Units.
