Industrial Bonding Tape

3M 4910 VHB Tape is a clear, solid-foam acrylic tape designed for structural bonding in assembly, manufacturing, automotive, aviation, construction, electronics, metalworking and general maintenance. It replaces mechanical fasteners such as screws, rivets or welds while distributing stress across the entire joint. The tape adheres to ABS, acrylic, glass, metal, nylon and polycarbonate surfaces for indoor and outdoor applications.

Continuous Roll Format

Supplied as a continuous roll measuring 12 in wide by 5 yd long with a 40 mil thickness, the tape includes a protective liner that is removed at the point of use. The roll format allows operators to cut custom lengths on site, reducing waste and fitting irregular geometries. Its conformable foam core fills surface gaps and tolerates differential thermal expansion between dissimilar substrates during daily service.

Wide Temperature Range

The tape maintains performance from -31 Degrees F to 194 Degrees F, making it suitable for environments that cycle between freezing and elevated heat. Buyers needing a thinner bond line, a different adhesive chemistry or a tape qualified for continuous immersion should evaluate alternative products.

Questions about this item

What temperature range does the 4910 VHB tape handle in practice?

The tape performs continuously from -31 °F up to 194 °F, so it remains bonded through freezing winters and hot engine bays without softening or becoming brittle.

What surface preparation and clearance does the 12-inch wide roll require for proper mounting?

Clean each substrate — ABS, acrylic, glass, metal, nylon or polycarbonate — with isopropyl alcohol, let it dry, then ensure the joint can accommodate the 40 mil foam thickness plus the liner before pressing the tape into place.

How is the 4910 VHB tape applied, and which step do installers most often skip?

Remove the liner, position the tape on the first surface, apply firm pressure across the full 12-inch width, then join the second surface and press again; the skipped step is the initial high-pressure seating on the first substrate before final assembly.
