Premium gray sealing tape with TPO backing, instant adhesion, UV resistant, and water-tight seal for industrial outdoor applications
3M™ Extreme Sealing Tape 4412G+ is a premium gray sealing solution designed for quick and clean sealing applications across industrial and construction environments. This 0.080 inch (2.0 mm) thick tape features a durable thermoplastic polyolefin (TPO) backing with a permanent acrylic adhesive that delivers instant adhesion to metals and plastics. The tape is engineered to eliminate the need for messy caulking equipment, cartridges, and the associated cure time, mess, and oozing problems of liquid sealants.
The rugged construction of 3M™ Extreme Sealing Tape 4412G+ provides exceptional resistance to sun, rain, and extreme temperatures ranging from 10°C to 93°C (50°F to 200°F). It effectively resists vibration, thermal expansion, and contraction while maintaining a water-tight seal over extended periods. The tape's flexibility allows it to conform seamlessly over fasteners, seams, joints, holes, and gaps, making it ideal for cargo trailer rail seals, HVAC enclosures, roof sealing, and various other outdoor applications.
This linerless design supports sustainability goals by eliminating traditional liner waste without compromising performance. Each case contains 6 rolls, with each roll measuring 2 inches wide by 18 yards long. The tape is available in multiple colors and thicknesses to suit diverse application requirements across construction, general industrial, MRO, metalworking, signage, solar, specialty vehicles, and transportation industries.
