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

The 3M™ 4411B+ is a high-quality, black sealing tape with a thickness of 1.0 mm – specifically designed for situations where reliable and immediate sealing is required. With its pressure-sensitive acrylic adhesive, it provides an immediate, clean bond—without any curing time or additional tools.
