Professional white sealing tape with instant adhesion, extreme weather resistance, and water-tight performance for industrial outdoor applications. Linerless design eliminates caulking mess.
The 3M™ Extreme Sealing Tape 4412W+ is a professional-grade sealing solution designed for quick and clean sealing applications in demanding outdoor and industrial environments. This white, 0.080 inch (2.0 mm) thick tape features instant adhesion and exceptional conformability, eliminating the need for messy caulking equipment and the associated cure times. The tape is engineered with a durable thermoplastic polyolefin (TPO) backing combined with a permanent acrylic adhesive, creating a flexible yet robust solution that conforms seamlessly over fasteners, seams, joints, holes, and gaps.
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 maintaining excellent performance against vibration and thermal expansion or contraction. The single-sided adhesive application method makes installation straightforward—simply apply by hand with pressure to metals and plastics to create water-tight seals. Its linerless design eliminates waste and supports sustainability goals without compromising performance.
Ideal for industrial applications including cargo trailer rail seals, HVAC enclosures, roof sealing, exterior side panel sealing, and truck and trailer roof sealing, this tape is available in a 6-roll case with each roll measuring 2 inches wide by 18 yards long. The product offers exceptional abrasion resistance, heat resistance, humidity resistance, and low-temperature resistance, making it suitable for both indoor and outdoor use across construction, general industrial, MRO, metalworking, signage, solar, specialty vehicles, and transportation industries.
