3M Extreme Sealing Tape 4412W+
3M Extreme Sealing Tape 4412W+ is a go-to solution for quick and clean sealing, bringing both excellent conformability and instant adhesion to eliminate the cure time, mess, and oozing associated with liquid sealants. Designed to stick with pressure to metals and plastics in order to cover edges, rivets, joints, splices, screw heads, holes and gaps, this tape dramatically simplifies the sealing process and removes the need for messy caulking equipment. However, while this tape makes application easy, it doesn’t compromise on toughness – delivering resistance to sun, rain, and extreme temperatures.
