3M™ Extreme Sealing Tape 4412G+
3M™ Extreme Sealing Tape 4412G+ is designed for sealing applications that require greater material depth and reliable protection against water intrusion. The flexible TPO backing conforms around screw heads, rivets, joints, splices, and other protrusions, while the linerless acrylic adhesive bonds to metals, plastics, and other surfaces as soon as pressure is applied. The tape seals instantly and reaches its ultimate bond strength 72 hours later.
Applications include: Sealing screw heads, rivets, joints, splices, and other protrusions to prevent water intrusion.
- 2.0 mm gauge, heaviest in the line
- Immediate seal on contact
- Linerless adhesive, less waste
- Bonds to metals, plastics, and other surfaces
- Ultimate bond strength in 72 hours
