Premium black sealing tape with 48-inch width and 36-yard length, featuring instant adhesion, rugged TPO backing, and linerless design for industrial exterior applications.
3M™ Extreme Sealing Tape 4411B+ is a premium black sealing solution engineered for quick and clean sealing applications in demanding industrial environments. This 48-inch wide tape delivers exceptional conformability and instant adhesion, eliminating the need for traditional messy caulking equipment, cure time, and oozing associated with liquid sealants. The tape features a durable thermoplastic polyolefin (TPO) backing combined with a permanent acrylic adhesive, providing superior performance in exterior applications where reliable, water-tight seals are essential.
Designed with rugged construction, this sealing tape resists sun, rain, extreme temperatures, vibration, and thermal expansion or contraction. The linerless design eliminates waste from traditional clear liners while maintaining exceptional performance standards. With a thickness of 0.040 inches (1.0 mm) and a 36-yard length per roll, this tape is ideal for cargo trailer rail seals, HVAC enclosures, roof sealing, and numerous industrial applications requiring durable exterior protection.
The 3M™ Extreme Sealing Tape 4411B+ combines ease of application with uncompromised toughness, delivering resistance to solvents, humidity, and low temperatures. Its single-coated design allows it to stick with pressure to metals and plastics, conforming over fasteners, seams, joints, holes, and gaps. This versatile tape supports sustainability goals while providing professional-grade sealing performance for construction, manufacturing, MRO, metalworking, transportation, and specialty vehicle applications.
