3M™ Extreme Sealing Tape 4412W+ is a white, very conformable, single-sided, pressure sensitive acrylic adhesive tape featuring TPO 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 is a go-to for quick and clean sealing. It sticks to metals and plastics without any mess. The tape molds to many shapes, covering edges, rivets, and screw heads for a tight seal that looks great. Plus, it comes in three colors to match most surfaces. Forget about caulking applicators and cartridges; this tape makes sealing simple. Its durable, abrasion resistant backing makes this tape a good choice for exterior applications. The acrylic adhesive adheres immediately after the application of pressure, enabling quick installation and the elimination of unnecessary downtime.
