Mounting tape 3M VHB 4910F, double-sided acrylic foam tape, 33 m × 20 mm

3M VHB 4910F is a double-sided acrylic foam mounting tape measuring 33 m in length and 20 mm in width. It provides a high-strength, long-lasting bond on many smooth, painted and coated surfaces, enabling concealed joining and replacement of mechanical fasteners in a range of indoor and sheltered outdoor applications. The tape has conformable foam that compensates for irregularities, offers vibration damping and creates a clean, flush finish where a discreet joint is required.

Advantages

The acrylic foam core delivers strong initial tack and durable adhesion over time without visible fasteners. Its double-sided adhesive formulation bonds to metals, glass, painted surfaces and many plastics while accommodating differential thermal expansion. The conformable carrier fills gaps and evens surface contact, and the tape resists moisture and common environmental factors in sheltered environments. Using 3M VHB 4910F reduces installation time and provides a neat aesthetic with consistent strength along the joint.

Suitable for

• Mounting signage, nameplates and decorative trim
• Attaching panels, moldings and control overlays
• Bonding metal, glass and painted substrates in light-duty assemblies
• Applications requiring vibration damping and flush, invisible fixing

Key specifications

• Format: double-sided acrylic foam tape
• Length: 33 metres
• Width: 20 millimetres
• Core: conformable acrylic foam for gap-filling
• Finish: pressure-sensitive adhesive on both sides
• Typical properties: high initial tack, durable adhesion, vibration damping

How to use

Prepare and clean both bonding surfaces thoroughly to remove oil, dust and contaminants; use an appropriate cleaner and allow surfaces to dry. Measure and cut the required length of 3M VHB 4910F with a sharp blade or scissors, and apply pressure when placing the tape to ensure full contact across the joint. Remove the liner and press the mating surface into place, maintaining firm pressure for several seconds. Allow time for the bond to develop; full bond strength is typically achieved over time as the adhesive flows and cures against the substrates.

Usage recommendations

For best results, apply the tape at room temperature and avoid use on heavily textured or contaminated surfaces. When bonding dissimilar materials, test a small sample to confirm compatibility. Use appropriate adhesive primers where recommended by 3M for low-energy plastics or special substrates. Follow safe cutting and handling practices and consult technical data from the manufacturer for detailed performance limits.
