3M™ Extreme Sealing Tape 4411G+
3M™ Extreme Sealing Tape 4411G+ is a 1.0 mm (0.040 in) sealing tape designed for demanding applications where water intrusion is a concern. Its flexible TPO backing readily conforms to screw heads, rivets, joints, splices, and other protrusions. The linerless acrylic adhesive bonds to metals, plastics, and other surfaces as soon as pressure is applied. The seal forms immediately, and the adhesive reaches its ultimate bond strength within the next 72 hours.
Applications include: Sealing screw heads, rivets, joints, splices, and other protrusions to prevent water intrusion.
- 1.0 mm gauge for demanding seals
- Immediate seal on contact
- Linerless adhesive, less waste
- Bonds to metals, plastics, and other surfaces
- Ultimate bond strength in 72 hours
