High-strength black acrylic foam bonding tape with 45 mil thickness, 3/4 inch width, and 36 yard length. Provides permanent adhesion to lightweight and dissimilar materials with temperature resistance up to 300°F. Ideal for replacing rivets, welds, and screws in industrial applications.
3M™ VHB™ Tape 4947F is a premium 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 innovative double-sided foam tape features advanced pressure-sensitive acrylic adhesive technology that provides extraordinary bonding strength while maintaining conformability on edges and contours. The tape is specifically designed to replace traditional fastening methods such as rivets, welds, screws, and liquid adhesives, offering significant time savings by eliminating drilling, welding, grinding, and project cleanup requirements.
The 4947F model comes in a convenient small pack format containing 3 rolls per case, with each roll measuring 0.75 inches wide by 36 yards long and 45 mil thickness with polyethylene film liner. This tape delivers seamless joining that keeps surfaces smooth and aesthetically pleasing, resulting in professional applications across multiple industries. It provides excellent bonding and sealing capabilities with closed-cell acrylic chemistry proven to withstand extreme environments, offering superior water resistance and long-term durability. The tape is UL GREENGUARD and UL GREENGUARD Gold Certified, contributing to LEED credit achievements for environmentally conscious projects.
With short-term temperature resistance up to 300°F (149°C) or long-term use withstanding 200°F (93°C), this versatile tape performs reliably in demanding conditions from extreme heat to cold climates. It effectively bonds to acrylic, aluminum, stainless steel, galvanized steel, composites, polycarbonate, ABS, wood, concrete, and more. The tape's excellent plasticizer resistance and chemical durability make it ideal for general industrial, transportation, appliance repair and assembly, construction, and signage applications. For industrial and occupational use only, this proven 3M innovation represents decades of adhesion science expertise.
