Professional white sealing tape with instant adhesion, UV resistance, and extreme temperature tolerance for industrial and outdoor applications. Linerless design eliminates caulking needs.
3M™ Extreme Sealing Tape 4412W+ is a professional-grade white sealing solution designed for quick and clean sealing applications across industrial and construction sectors. This 0.080 inch (2.0 mm) thick tape features instant adhesion technology that eliminates the need for traditional caulking equipment, cure time, and messy liquid sealants. The tape is engineered with an acrylic adhesive on a durable thermoplastic polyolefin (TPO) backing that provides excellent conformability over fasteners, seams, joints, holes, and gaps.
Built for extreme outdoor conditions, this tape delivers exceptional resistance to sun, rain, extreme temperatures ranging from 10°C to 93°C (50°F to 200°F), vibration, and thermal expansion or contraction. The linerless design eliminates waste common with traditional sealing solutions while maintaining superior performance. It is ideal for cargo trailer rail seals, HVAC enclosures, roof sealing, exterior side panel sealing, and other demanding industrial applications where water-tight seals are critical.
The 4412W+ comes as a 2-roll case with each roll measuring 4 inches wide by 18 yards long, providing 36 total yards of premium sealing tape. With UV resistance, humidity resistance, abrasion resistance, and low temperature resistance, this tape is suitable for both indoor and outdoor applications in construction, general industrial, MRO, metalworking, signage, solar, specialty vehicles, and transportation industries.
