3M Extreme Sealing Tape, also referred to as “single sided VHB™ tape” is a flexible, tough, single coated tape that conforms over edges, contours and even screws and rivets. 3M™ acrylic technology absorbs vibrations and holds securely through sun, rain, snow, temperature extremes and humidity for an instant seal that rolls on fast and looks good. Extreme Sealing Tape saves time and money by eliminating the need for additional tools that require storage and cleaning, and create unnecessary waste.
3M™ Extreme Sealing Tape sticks immediately to metals, plastics and other substrates without drying time, dripping, oozing, or clean-up. Simply unwind the tape and press it into place to provide a water and airtight seal or seam.
It is often required to overlap 3M™ Extreme Sealing Tape onto itself. In this case, the ionomer backing of the first piece is one of the substrates to which the second piece of tape is bonding. The tapes should overlap at least 2 cm (3/4 in).
Material Info & Colors
Conformable 3M™ acrylic forms an even bond over contours, edges, rivets and screws for a water tight seal while the tough ionomer backing resists abrasions and harsh outdoor conditions. Proven 3M™ adhesive tape even bonds to itself for unbeatable performance on overlapping seams and joints.
