Premium dark gray VHB foam tape with high-temperature resistance up to 450°F, ideal for metal bonding and industrial assembly applications requiring superior strength and durability.
3M™ VHB™ Tape 4611 is a premium dark gray, double-sided foam tape engineered for high-temperature industrial bonding applications. This advanced adhesive solution features a general-purpose acrylic adhesive combined with a firm acrylic foam core, delivering a total thickness of 45 mil (1.1 mm). The tape provides immediate handling strength with no curing time required, making it an ideal replacement for traditional mechanical fasteners such as rivets, welds, and screws. With exceptional high-shear strength and thermal resistance, this tape excels in bonding high surface energy (HSE) substrates including aluminum, galvanized steel, and stainless steel with minimal surface preparation.
The 3M VHB Tape 4611 is specifically designed to withstand demanding temperature conditions, maintaining performance during long-term applications at temperatures up to 300°F (149°C) and short-term applications at 450°F (232°C). This makes it particularly suitable for assembly processes that precede high-temperature paint ovens. The closed-cell acrylic chemistry provides superior water and moisture resistance, creating a tight seal that protects bonded assemblies from environmental exposure. The tape's unique formulation balances strength, viscoelasticity, and adhesion, offering a smooth and seamless bonding solution that allows the use of thinner, lighter-weight, and dissimilar materials compared to traditional fastening methods.
This versatile industrial tape finds application across numerous markets including window and door assembly, electronics, signage, construction, automotive, and general manufacturing. Each case contains 3 rolls of 36 yards (32.9 m) length with a 3-inch (76.2 mm) width, providing ample material for production environments. The tape eliminates the need for drilling, welding, grinding, and finishing work, significantly increasing operational efficiency while delivering long-term durability and consistent bonding performance.
