High-strength industrial bonding tape with conformable foam core, permanent adhesion to dissimilar materials, temperature resistant to 300°F, replaces rivets and welds, UL GREENGUARD certified.
3M™ VHB™ Tape 4947F is a high-strength acrylic bonding solution engineered with a conformable foam core that adheres quickly and permanently to a variety of thin, lightweight, and dissimilar materials. This industrial-grade double-sided foam tape features advanced pressure-sensitive acrylic adhesive technology that provides immediate handling strength and permanent bonding, making it an ideal substitute for traditional mechanical fasteners such as rivets, welds, and screws. The tape delivers excellent shear strength, conformability, and surface adhesion while maintaining superior temperature resistance for both short-term and long-term applications.
With dimensions of 600mm (23.622 inches) in width and 33 meters (36.089 yards) in length, this black polyethylene film-lined tape is specifically designed for industrial and occupational applications across multiple sectors. The 45 mil thickness provides optimal balance between conformability and structural integrity. The closed-cell acrylic chemistry is proven to withstand extreme environments, offering excellent resistance to moisture, solvents, and plasticizers. The tape performs reliably in short-term applications at temperatures up to 300°F (149°C) and long-term use at temperatures up to 200°F (93°C).
This versatile bonding solution is ideal for applications including decorative material and trim attachment, nameplate and logo mounting, electronic display assembly, panel-to-frame bonding, and stiffener attachment. The tape's ability to conform to edges and contours while providing a tight water-resistant seal makes it perfect for transportation, appliance, electronics, construction, signage, and general industrial applications. UL GREENGUARD and UL GREENGUARD Gold Certified, the 4947F contributes to LEED credit achievement while eliminating the need for drilling, grinding, refinishing, screwing, and welding processes.
