Waterproof Butyl Tape Construction and size: Aluminum foil base surface with butyl rubber; 5 cm x 5 m, thickness 1.2 mm. Designed for longlasting performance with aging resistance up to 30 years. Key benefits: Provides a reliable waterproof seal with viscosity and strong stretch while remaining flexible. Capable of handling thermal expansion, contraction, and mechanical deformation without hardening or losing seal. Durability and temperature tolerance: Can be used at 40°C (40°F) without cracking or deformation. Surface must be clean and dry for adhesion; simply peel off the release liner, apply to the surface, and press firmly to seal leaks. Allweather performance: Suitable for indoor and outdoor repairs. It maintains performance under varying weather conditions and does not solidify during use. Applications: Ideal for allweather repairs including RV/Camper roofs, plastic sheeting, vents, cars, pipes, drains, hose gouges, cracks, windows, boats, sprinkler systems, doors, and walls. How to use (simple steps): Ensure the surface is clean and dry. Peel the release liner, apply the tape over the target area, and apply firm pressure to activate the seal. Use scenarios (illustrative examples): Sealing leaks on an RV or camper roof around vents or seams. Repairing leaks in pipes, drains, or hose fittings in outdoor or vehicle applications. Temporarily or permanently sealing cracks or joints on boats, windows, doors, or walls.
