3M™ Extreme Sealing Tape 4411W+
3M™ Extreme Sealing Tape 4411W+ is a white, 1.0 mm (0.040 in) sealing tape designed to prevent water intrusion at screw heads, rivets, joints, splices, and other protrusions. Its flexible TPO backing conforms closely to these surfaces, and the linerless acrylic adhesive bonds to metals, plastics, and other surfaces on contact. The tape seals immediately and continues to build toward its ultimate bond strength over the next 72 hours.
Applications include: Sealing screw heads, rivets, joints, splices, and other protrusions to prevent water intrusion.
- White finish, 1.0 mm gauge
- Seals on contact
- Linerless adhesive, less waste
- Bonds to metals, plastics, and other surfaces
- Ultimate bond strength in 72 hours
