Double-sided tape 3M VHB 4611F, dark gray, 19 mm x 1.1 mm x 33 m

3M VHB 4611F double-sided tape in dark gray, 19 mm × 1.1 mm × 33 m, is a structural bonding tape engineered for permanent, high-strength assemblies. The acrylic foam core and pressure-sensitive adhesive form an immediate tack and long-term durable bond to a variety of substrates including metals, painted surfaces, glass, plastics and composites. With a medium-thickness foam carrier, the tape offers vibration damping and gap-filling ability to accommodate uneven surfaces and distribute stress across bonded joints.

Advantages

The tape provides high shear and peel strength combined with conformability to irregular substrates. Its acrylic adhesive is formulated for long-term durability, UV resistance and temperature stability within typical use ranges. The dark gray color minimizes visibility on darker panels and the foam core compensates for small surface variations while reducing transmitted vibration. The product enables quick, clean application without mechanical fasteners and supports a sealed joint when pressed into place.

Suitable for

• Permanent bonding of metal trims, nameplates and overlays
• Joining plastic and composite parts where mechanical fasteners are undesirable
• Mounting electronic or decorative panels in household appliances
• Sealing and vibration damping in repair and retrofit tasks

Key specifications

• Adhesive type: pressure-sensitive acrylic
• Carrier: closed-cell acrylic foam
• Color: dark gray
• Width: 19 mm
• Thickness: 1.1 mm
• Length (roll): 33 m
• Properties: high shear strength, gap filling, vibration damping, UV resistance

How to use

Ensure both surfaces are clean, dry and free of dust, oil or release agents. For best adhesion, clean non-porous substrates with isopropyl alcohol and allow to dry. Cut the required length from the roll, peel back the liner and apply the tape to one surface with firm, even pressure to ensure contact. Remove the remaining liner and press the second surface into place, applying sustained pressure over the bonded area to increase initial bond strength. Full bond strength develops over time and may be accelerated by applying heat within the product’s recommended temperature range.

Usage recommendations

Use at room temperature for optimal handling; select compatible surface treatments for low-energy plastics. Avoid relying on the tape alone for structural loads where codes or safety requirements mandate mechanical fasteners. Store rolls in a cool, dry place away from direct sunlight and extreme temperatures to maintain adhesive performance.
