Premium high-strength acrylic bonding tape with conformable foam core for permanent adhesion to diverse materials. Industrial-grade double-sided tape replaces rivets, welds, and screws while providing water-resistant sealing and temperature resistance up to 300°F.
3M™ VHB™ Tape 4947F is a premium high-strength acrylic bonding solution engineered with a conformable foam core that delivers immediate and permanent adhesion to a wide variety of thin, lightweight, and dissimilar materials. This industrial-grade double-sided foam tape features advanced pressure-sensitive acrylic adhesive technology that replaces traditional mechanical fasteners such as rivets, welds, and screws while significantly reducing assembly time and labor costs. The tape's superior conformability allows it to bond securely to edges and contours, providing an exceptional tight seal against water and environmental elements.
Designed for professional industrial applications, 3M™ VHB™ Tape 4947F offers exceptional performance across diverse substrates including aluminum, stainless steel, galvanized steel, composites, plastics, acrylic, polycarbonate, ABS, and painted or sealed wood and concrete. The tape maintains outstanding performance in extreme temperature environments, withstanding short-term use at temperatures up to 300°F (149°C) and long-term continuous use at temperatures up to 200°F (93°C). Its closed-cell acrylic chemistry provides excellent resistance to moisture, solvents, plasticizers, and UV exposure, making it suitable for both indoor and outdoor applications across multiple industries.
This VHB™ Tape 4947F comes in a convenient small pack format with 2 rolls per case, each roll measuring 1 inch wide by 36 yards long with a 45 mil thickness and polyethylene film liner. The product is UL GREENGUARD and UL GREENGUARD Gold Certified, contributing to LEED credit requirements for sustainable construction projects. Ideal for decorative trim, nameplates, logos, electronic displays, panel-to-frame bonding, and stiffener applications, this tape eliminates the need for drilling, grinding, refinishing, screwing, and welding while delivering a seamless, professional appearance.
