3M VHB 4611F Double-Sided Tape Dark Grey (various sizes)

3M™ VHB™ 4611F is a durable, double-sided foam tape designed for permanent bonding of high surface energy materials, such as metals. The dark grey acrylic adhesive on a tough 1.1 mm foam provides high temperature resistance and allows bonding without the need for drilling, riveting, or welding. VHB™ bonding technology enables strong, aesthetic, and almost invisible joints.

• Substrate compatibility: metals (aluminum, stainless steel, galvanized steel), glass, HSE plastics

Application:

• Mounting stiffeners, panels, and frames
• Attaching decorative materials and ornaments
• Installing nameplates and badges
• Permanent bonding before heat treatment (e.g., powder coating)
• Industrial applications in the metal, automotive, home appliances, advertising, and many other industries

Benefits and features:

✅ Permanent fastening – no need for screws, rivets, or welding
✅ Aesthetics – practically invisible joints maintaining surface smoothness
✅ Thermal resistance – suitable for high-temperature applications
✅ Quick and clean application – bonding technology without mess and the need for cleaning
✅ Versatility – adhesion to a wide range of high surface energy materials

Application tips:

Before application, surfaces should be cleaned and degreased (e.g., with isopropyl alcohol). Apply the tape and press firmly to activate the adhesive. Maximum bond strength is achieved after 72 hours at room temperature. The tape is also ideal for applications subject to further thermal processing.
