About Butyl Rubber: The Super Waterproof Tape is commonly known as foil tape. These tapes feature butyl rubber that is extruded, permanently tacky, and pressure-sensitive with strong adhesion. They form an instant seal against water, air, and dust, and remain permanently flexible. Ideal for sealing joints and filling gaps on bolt-on duct flanges, circular ducts in HVAC systems, air conditioner casings, roofing and cladding systems, caravan roofs and panels, automotive windshields and tail lights, glass, and metal.PRODUCT FEATURES: - Resistant to chemicals, heat, and weather - High tack adhesive performance in cold temperatures - Excellent insulation properties and flame resistance - Strong adherence even in low temperatures - Blocks moisture and odors - Water and UV resistant MULTI-APPLICATION: Suitable for use in electrical, HVAC, and construction industries. Specifically designed for applications requiring moisture and chemical resistance, thermal conductivity, flame resistance, and heat and light reflectance. Performs well under various weather conditions.TIPS: - Due to high adhesion, wear gloves during application to avoid sticking to hands. - In cold conditions, warm the tape with a hair dryer before application. - Avoid disturbing or removing the tape within 24 hours after application. - Do not use with solvents such as benzene, ethylene, or silicone-based materials.SPECIFICATIONS: - Material: Aluminum foil, butyl rubber - Sizes: 2 in x 16.4 ft, 4 in x 16.4 ft, 6 in x 16.4 ft PACKAGE INCLUDES: 1 x Super Waterproof Tape
