Premium industrial sealing tape with high-tack acrylic adhesive, UV-resistant for 12 months, waterproof membrane, and superior moisture barrier protection for difficult-to-stick surfaces.
3M™ Sealing Tape 8777 is a premium translucent sealing solution engineered for demanding industrial applications requiring reliable moisture barrier protection. This self-adhered tape features a proprietary film backing with high-tack acrylic adhesive on a convenient split liner, specifically designed to seal difficult-to-stick surfaces including damp and challenging substrates. The tape combines exceptional durability with superior adhesive performance, delivering an air barrier and waterproof membrane that prevents moisture intrusion around nails, staples, and penetrations.
Built with a tough yet conformable backing that resists punctures and tears during application, this sealing tape excels in extreme temperature environments ranging from -40°F to 176°F (-18°C to 80°C). The UV-resistant formulation maintains performance for up to 12 months of outdoor exposure, while the aggressive acrylic adhesive remains effective at both low and high application temperatures without melting or staining. The thin, flexible backing conveniently fits into corners and tight spaces, making installation efficient and accurate.
This industrial-grade tape is ideal for exterior side panel sealing, deck joist and header board sealing, and window and door opening sealing against moisture intrusion. Each pallet contains 25 rolls of 75-foot length tape at 60 inches wide, providing substantial coverage for large-scale construction and maintenance projects. Engineered for professional use by trained industrial workers in construction, automotive, marine, and general industrial applications.
