3M™ Extreme Sealing Tape 4411W+ is a professional-grade white sealing solution designed for quick and clean sealing applications across industrial and commercial environments. This 0.040 inch (1.0 mm) thick tape features a durable thermoplastic polyolefin (TPO) backing with acrylic adhesive that delivers instant adhesion to metals and plastics. The tape is engineered to cover edges, rivets, joints, splices, screw heads, holes, and gaps while eliminating the need for messy caulking equipment, cartridges, and lengthy cure times associated with traditional liquid sealants.
The rugged construction of this sealing tape provides exceptional resistance to sun, rain, and extreme temperatures ranging from 10°C to 93°C (50°F to 200°F), making it ideal for outdoor and industrial applications. Its UV-resistant properties and water-tight seal ensure reliable performance in challenging environmental conditions including exposure to humidity, thermal expansion, vibration, and various solvents. The tape's excellent conformability allows it to flex and adapt over fasteners, seams, joints, and irregular surfaces without compromising its sealing integrity.
This linerless design eliminates the waste associated with traditional clear liners, supporting sustainability initiatives while maintaining superior performance. The 3M™ Extreme Sealing Tape 4411W+ is available in a convenient 6-roll case with each roll measuring 2 inches wide by 36 yards long, making it suitable for cargo trailer rail seals, HVAC enclosures, roof sealing, exterior side panel sealing, and numerous other industrial applications.
