Double-sided VHB Tape 3M 4910F, 20 mm x 33 m

3M VHB Tape 4910F is a high-strength double-sided acrylic foam adhesive tape sized 20 mm x 33 m, developed for permanent bonding where mechanical fasteners are not desirable. The conformable foam core compensates for minor surface irregularities and provides uniform adhesion across metals, plastics and painted surfaces. Its thin profile allows discreet joints while delivering solid shear and peel performance for industrial assembly, glazing trim, signage and repair tasks.

Advantages

The tape delivers strong long-term adhesion with good resistance to vibration and dynamic loads, producing clean joints without drilling or visible fasteners. Its acrylic adhesive maintains performance over a wide temperature range and bonds reliably to a variety of rigid and semi-rigid substrates. The product's foam carrier helps absorb stresses from thermal expansion and reduces the need for mechanical stress-relief features.

Suitable for

• Permanent bonding of metal panels and trims
• Mounting plastic components and decorative mouldings
• Signage attachment and nameplates
• Automotive and industrial repair where concealed fastening is required
• Bonding painted surfaces and coated substrates

Key specifications

• Width: 20 mm
• Length: 33 m
• Tape type: Double-sided acrylic foam tape
• Carrier: Conformable foam core for gap filling
• Adhesive chemistry: Acrylic adhesive for long-term bonding
• Typical applications: Metal, plastic, painted surfaces
• Performance: Good shear and peel resistance; vibration damping

How to use

Ensure both bonding surfaces are clean, dry and free of oil, dust and loose particles. For best results, clean substrates with isopropyl alcohol or a suitable solvent and allow to dry. Cut the tape to the required length, remove the liner and apply pressure to engage adhesive contact across the entire joint. For thicker gaps or uneven substrates, apply uniform firm pressure or use a roller to ensure full surface contact. Allow bonded assemblies to rest undisturbed to achieve maximum bond strength according to the adhesive's cure profile.

Usage recommendations

Select appropriate surface preparation and test adhesion on representative materials before production use. Avoid applying the tape at temperatures below the recommended handling range; elevated ambient temperature during assembly can improve initial tack. For structural or safety-critical joints, consider mechanical backup or engineering validation to confirm suitability.
