What this tape is and who uses it

3M 4930 VHB is a white, double-sided acrylic foam tape supplied in a 1 in by 15 ft roll. The firm core and general-purpose adhesive create permanent bonds that replace mechanical fasteners such as rivets, screws and welds. It is suited for engineers, fabricators and maintenance teams who need structural strength without drilling or grinding.

Capacity and headroom

The tape is 0.025 in (0.6 mm) thick and adheres to aluminium, stainless steel, galvanised steel, composites, plastics, acrylic, polycarbonate, ABS, painted or sealed wood and concrete. It delivers high shear strength and temperature resistance for permanent indoor and outdoor assemblies. Very low-surface-energy substrates or continuous immersion may exceed its reliable adhesion range.

What it replaces and when the jump is worth it

4930 belongs to the 4950 family and directly substitutes rivets, spot welds and screw joints, eliminating drilling, grinding, refinishing and clean-up. The switch is worthwhile when design flexibility, vibration damping or a clean appearance outweigh the cost of mechanical hardware. It is not for buyers who need removable or repositionable fastening.

Questions about this item

Will the 4930 tape bond to the aluminium and painted wood I already have?

The acrylic adhesive bonds to aluminium, stainless steel, galvanised steel, composites, plastics, acrylic, polycarbonate, ABS and painted or sealed wood and concrete.

How can I verify the 4930 tape is holding at full strength after application?

Apply firm pressure during installation; the viscoelastic foam core conforms to surfaces and develops high shear strength for permanent bonds.

Does the 1 in x 15 ft roll include a dispenser or must I buy one separately?

The roll is supplied on a 3 inch diameter core; no dispenser is included and must be purchased separately if required.
