High-strength acrylic double-sided foam bonding tape with conformable core, immediate permanent adhesion, temperature resistant to 300°F, replaces rivets and welds, 1 inch x 36 yard rolls, 9 per case.
The 3M™ VHB™ Tape 4947F is a high-strength acrylic bonding solution engineered with a conformable foam core that provides immediate and permanent bonding to a variety of thin, lightweight, and dissimilar materials. This industrial-grade double-sided foam tape features advanced pressure-sensitive acrylic adhesive technology that delivers exceptional shear strength, conformability, and surface adhesion. The tape is specifically designed to replace traditional mechanical fasteners such as rivets, welds, and screws, while providing seamless joining that keeps surfaces smooth and aesthetically pleasing for professional applications.
With its closed-cell acrylic chemistry, the 3M™ VHB™ Tape 4947F offers excellent bonding and sealing capabilities that withstand extreme environments. The tape performs reliably in short-term applications at temperatures up to 300°F (149°C) and maintains long-term durability at temperatures up to 200°F (93°C). It features exceptional plasticizer resistance and can be effectively used on acrylic, aluminum, stainless steel, galvanized steel, composites, polycarbonate, ABS, wood, concrete, and many other substrates. The polyethylene film liner ensures easy application and precise control during installation.
This 9-roll case contains rolls measuring 1 inch in width by 36 yards in length with a 45 mil total thickness, making it ideal for industrial, transportation, appliance repair and assembly, construction, and signage applications. The tape is UL GREENGUARD and UL GREENGUARD Gold Certified, contributing to LEED credits and environmental sustainability initiatives. Engineered for immediate handling strength and permanent bonding, the 3M™ VHB™ Tape 4947F eliminates the need for drilling, grinding, refinishing, screwing, and welding, significantly reducing project time and labor costs.
