Premium white foam bonding tape with 0.045 inch acrylic adhesive for permanent fastening, replacing rivets, welds and screws in industrial applications
3M™ VHB™ Tape 4951 is a revolutionary white foam bonding tape featuring a 0.045 inch (1.1 mm) low temperature applicable acrylic adhesive on both sides of a firm acrylic foam core. This permanent bonding solution provides exceptional strength and long-term durability, making it an ideal replacement for mechanical fasteners such as rivets, welds, and screws. The tape measures 24 inches in width and comes in a 36-yard roll with a 3-inch core, offering substantial coverage for industrial bonding applications.
Designed for versatile use across multiple substrates including metals, glass, high surface energy paints, and plastics, this specialty tape delivers immediate handling strength through its pressure-sensitive adhesive technology. The VHB 4951 creates a permanent seal against water, moisture, and environmental contaminants while eliminating the need for drilling, grinding, refinishing, and associated cleanup processes. Its unique viscoelastic properties allow for design flexibility and enable the use of thinner, lighter weight, and dissimilar materials in assembly applications.
With a maximum operating temperature of 300°F (149°C) and a 24-month shelf life, this tape is suitable for both indoor and outdoor applications across diverse industries including appliance manufacturing, consumer goods, signage, transportation, and general industrial use. 3M™ VHB™ Tape 4951 represents decades of innovation in adhesive technology, proven reliable in applications ranging from skyscrapers and cell phones to electronic highway signs, refrigerators, and architectural windows.
