3M™ Extreme Sealing Tape 4410B+
3M™ Extreme Sealing Tape 4410B+ is designed for sealing applications where reliable protection against water intrusion is critical. The flexible black TPO backing conforms easily to screw heads, rivets, joints, splices, and other protrusions, while the linerless acrylic adhesive adheres immediately to metals, plastics, and other surfaces. It reaches ultimate bond strength 72 hours after pressure is applied, but it provides immediate sealing.
Applications include: Sealing screw heads, rivets, joints, splices, and other protrusions to prevent water intrusion.
- Immediate seal, no cure time or mess
- Linerless adhesive, less waste
- Bonds to metals, plastics, and other surfaces
- Full bond strength in 72 hours
