3M™ Extreme Sealing Tape 4411B

3M™ Extreme Sealing Tape 4411B is a black, highly conformable, single-sided, pressure sensitive acrylic adhesive tape with a high performance ionomer backing. It is an ideal solution for creating a watertight seal. It conforms over fasteners, seams, joints, holes, and gaps to ensure a long-lasting seal on a variety of substrates.

3M™ Extreme Sealing Tape 4411B is a black, 0.040 in (1.0 mm) thick tape featuring a flexible backing that easily conforms over screw heads, rivets, joints, splices, and other protrusions to provide protection from water intrusion. The durable, abrasion resistant backing makes this tape a good choice for outdoor applications where exposure to weather is a concern. Since it can be painted, you can match most existing colours to blend seamlessly into the surrounding area while retaining the water tight bond. The soft, yet thick acrylic adhesive adheres immediately, allowing for quick application and eliminating unnecessary downtime. This adhesive not only bonds instantly to a variety of substrates, but it also adheres well to itself in order to maintain a consistent seal while creating overlapping joints. A backside liner ensures easy handling and application of the tape. Ideal for heat sealing and waterproofing.
