Professional white sealing tape with instant adhesion, extreme temperature resistance, and water-tight protection for industrial and outdoor applications.
3M™ Extreme Sealing Tape 4411W+ is a professional-grade white sealing solution designed for quick and clean sealing applications across industrial and outdoor environments. This versatile tape features a single-coated acrylic adhesive on a durable thermoplastic polyolefin (TPO) backing that delivers exceptional conformability and instant adhesion without requiring cure time. The tape is engineered to stick securely to metals and plastics, effectively covering edges, rivets, joints, splices, screw heads, holes, and gaps while eliminating the need for messy caulking equipment and cartridges.
Built for extreme conditions, this sealing tape delivers outstanding resistance to sun, rain, and extreme temperatures ranging from 10°C to 93°C (50°F to 200°F), while also resisting vibration, thermal expansion, and contraction. The rugged construction includes resistance to solvents and humidity, making it ideal for exterior applications where a reliable, water-tight seal is essential. The linerless design eliminates traditional liner waste, supporting sustainability goals without compromising performance or durability.
Available in a convenient 3-roll case format with each roll measuring 3 inches wide by 36 yards long, this tape is engineered for cargo trailer rail seals, HVAC enclosures, roof sealing, truck and trailer applications, and general industrial sealing needs. The flexible TPO backing conforms perfectly over fasteners, seams, and irregular surfaces, while the permanent acrylic adhesive ensures long-lasting performance in both indoor and outdoor environments.
