Professional-grade double-sided foam tape with 90 mil thickness, providing permanent bonding for metal, plastic, and composite materials without fasteners or adhesive curing.
3M™ VHB™ Tape 4991 is a premium double-sided foam tape comprised of a multi-purpose acrylic adhesive with a conformable foam core backed on a polyethylene film liner, delivering a total thickness of 90 mil (2.3 mm) when applied. This professional-grade bonding tape provides an excellent balance of strength, conformability, and adhesion to high and medium surface energy materials, making it a smooth, seamless alternative to rivets, welds, and screws. The tape features closed-cell acrylic chemistry proven to withstand extreme environments and offers exceptional durability in both indoor and outdoor applications.
Designed for industrial and occupational use, 3M™ VHB™ Tape 4991 delivers immediate handling strength without requiring fixture time or cure waiting periods, making it ideal for rapid assembly processes. The tape's unique viscoelastic properties enable it to adhere to a broad range of substrates including aluminum, stainless steel, galvanized steel, composites, plastics, acrylic, polycarbonate, ABS, and painted or sealed wood and concrete. With maximum operating temperatures up to 250°F (121°C), this tape maintains its bonding integrity across extreme temperature variations, from the heat of Dubai to the cold of Canada.
Commonly used across multiple industries including transportation, appliance manufacturing, electronics, construction, sign and display, and general industrial applications, this tape is UL GREENGUARD™ and UL GREENGUARD™ Gold Certified, helping contribute to LEED® credits. The 4991 model is specifically engineered for applications such as decorative material and trim attachment, nameplate and logo mounting, electronic display assembly, panel-to-frame bonding, and stiffener-to-panel fastening. Each roll measures 24 inches in width by 36 yards in length, providing ample material for large-scale industrial bonding and sealing projects.
