3M Adhesive Tape 4411B+ Black

3M™ 4411B+ High-Performance Sealing Tape – Black sealing solution for demanding applications

The 3M™ 4411B+ is a high-quality, black sealing tape with a thickness of 1.0 mm, specifically developed for complex sealing tasks. Thanks to its pressure-sensitive acrylic adhesive, it bonds instantly and enables fast and clean sealing—without any curing time, cartridges, or tools.

The elastic TPO backing conforms perfectly to irregular shapes such as screw heads, joints, gaps, or rivets, ensuring a durable, watertight seal. Particularly practical: The tape is linerless – this simplifies handling and reduces waste.

Thanks to its high weather and abrasion resistance, the 4411B+ is ideal for outdoor applications in industrial, technical, or construction-related areas. The black color ensures a discreet, clean appearance on dark surfaces.
