3M™ Extreme Sealing Tape 4411+ for Heavy-Duty Watertight Sealing
3M 4411+ Extreme Sealing Tape is a 40 mil (1.0 mm) thick, single-sided, pressure-sensitive acrylic tape designed for demanding sealing applications. It delivers an instant, watertight bond to metals, plastics, and other difficult substrates—no cure time or mess required. The thicker TPO backing improves conformability and gap-filling, creating a durable seal over rivets, seams, and joints in exterior and industrial environments.
Note: For enhanced sealing performance, 3M Extreme Sealing Tape is commonly used alongside 3M Industrial Sealing Tape IS1 in demanding outdoor or vehicle applications.
