3M 068060-75942 Extreme Sealing Tape, 4412G+, 3 In X 18 Yd X 80 Mil, Gray

The 3M Extreme Sealing Tape 4412G+ is a thick, gray, 80 mil tape designed to create an immediate, watertight seal in difficult applications where traditional liquid sealants are messy or take too long to cure. It uses a strong acrylic adhesive that sticks instantly to metals and plastics, providing a durable and flexible barrier against the elements.

• Immediate sealing: Unlike liquid products, this tape seals instantly upon pressure, eliminating downtime associated with waiting for curing.
• Superior conformability: The flexible Thermoplastic Polyolefin (TPO) backing easily conforms over irregular surfaces like rivets, screws, and seams, ensuring a complete and reliable seal.
• Excellent durability for exterior use: The tough, abrasion-resistant backing and acrylic adhesive make it a great choice for long-term exterior sealing, even in harsh environments.

Who this is best for

This tape is ideal for maintenance and repair professionals in transportation (truck/trailer roof sealing), HVAC, and general industrial environments who need a fast, clean, and durable seal for seams, joints, and holes.
