Premium dark gray double-sided VHB foam tape with high-temperature resistance up to 450°F, ideal for metal bonding and industrial assembly applications without curing time required.
3M™ VHB™ Tape 4611 is a premium dark gray, double-sided foam tape engineered for high-temperature industrial bonding applications. This specialized tape features a general-purpose acrylic adhesive combined with a firm acrylic foam core, delivering a total thickness of 45 mil (1.1 mm) when applied. The tape requires no curing time and provides immediate handling strength, making it an ideal alternative to traditional mechanical fasteners such as rivets, welds, and screws. With its advanced closed-cell acrylic chemistry, this tape creates a tight seal against water and moisture while maintaining exceptional bond strength across a variety of high surface energy (HSE) substrates including aluminum, galvanized steel, and stainless steel.
The 4611 tape excels in high-temperature environments, withstanding long-term use at temperatures up to 300°F (149°C) and short-term applications at 450°F (232°C), making it particularly suitable for bonding prior to high-temperature paint processing. This versatile bonding solution delivers high shear strength and thermal resistance while offering a smooth, seamless finish that eliminates the need for drilling, welding, grinding, and other finishing work. The tape's superior performance across numerous industries—including window and door assembly, electronics, signage, construction, and general industrial applications—has made it a trusted solution for over four decades.
Each case contains 18 rolls of tape, with each roll measuring 1/2 inch (12.7 mm) in width and 36 yards (32.92 m) in length. The polyethylene film liner ensures easy application and consistent performance. 3M™ VHB™ Tape 4611 allows manufacturers to use thinner, lighter-weight, and dissimilar materials compared to traditional fastening methods while maintaining superior durability and reliability. This proven tape offers outstanding solvent and moisture resistance, excellent UV stability, and consistent bonding performance in both indoor and outdoor environments.
