High-strength acrylic foam tape with immediate bonding, 7.25 in x 36 yd, rated for extreme temperatures and multiple substrates. Industrial-grade solution replacing rivets, welds, and screws.
3M™ VHB™ Tape 4947F is a premium high-strength acrylic bonding solution engineered with a conformable foam core that provides immediate and permanent adhesion to a wide variety of thin, lightweight, and dissimilar materials. This innovative double-sided foam tape combines exceptional strength with remarkable conformability, featuring closed-cell acrylic chemistry proven to withstand extreme environments. The tape measures 7.25 inches in width and 36 yards in length with a 45 mil thickness and polyethylene film liner, making it ideal for professional industrial applications requiring reliable, long-lasting bonds.
Designed as a proven substitute for traditional mechanical fasteners like rivets, welds, and screws, 3M VHB Tape 4947F eliminates the need for drilling, grinding, refinishing, and welding, significantly saving time and labor costs. The pressure-sensitive adhesive technology provides excellent water resistance and tight sealing capabilities, with high-temperature resistance suitable for short-term use up to 300°F (149°C) or long-term use withstanding up to 200°F (93°C). Its versatile composition allows effective bonding to acrylic, aluminum, stainless steel, galvanized steel, composites, polycarbonate, ABS, wood, concrete, and numerous other substrates.
This tape is UL GREENGUARD and UL GREENGUARD Gold Certified, contributing to LEED credit achievements in construction projects. The 4947F variant from the renowned 4941 family of VHB tapes is specifically engineered for excellent adhesion to metals, glass, and medium to high surface energy materials. With applications spanning transportation, appliance manufacturing, electronics, construction, signage, and general industrial use, this conformable foam tape delivers consistent bonding performance indoors and outdoors while maintaining outstanding durability and exceptional solvent and moisture resistance.
