Features 1. Our butyl waterproof tapes can seal leaks quickly and efficiently. 2. Superior waterproof performance with high viscosity and strong elongation, while maintaining flexibility. The product does not harden, allowing it to accommodate thermal expansion, contraction, and mechanical movement of bonded surfaces. 3. This waterproof butyl tape offers excellent resistance to high and low temperatures, performing reliably up to 80°C (176°F) without melting and down to -40°C (-40°F) without cracking. The tape's textured surface provides enhanced durability, abrasion resistance, corrosion resistance, and slip resistance. 4. Ideal for sealing roof leaks, RV and tent windows, awnings, sunrooms, outdoor equipment, gutters, metal structures, downspouts, boats, mobile homes, PVC and plumbing pipes, sprinkler systems, seams, doors, walls, vents, air ducts, HVAC systems, and various DIY applications. 5. Easy to apply: Clean and dry the surface, peel off the release liner, and apply the butyl tape directly to the area.
