Double sided Dual lock® tapes

3M™ Dual Lock™ double-sided adhesive tapes comprise two support strips made of a thick polypropylene film with protruding plastic connectors on one side of the support and the other side coated with adhesive, or left uncoated.

When no adhesive is applied to the support, the Dual Lock™ tape may be stitched or stapled.

Acrylic or rubber adhesives may be used.

The flexible connectors have mushroom-shaped heads, and when two strips of Dual Lock™ are pressed together, the heads interlock instantaneously to create a secure fastening. An audible “snap” indicates that the tapes have locked together.

Dual Lock™ fastenings can replace traditional mechanical fastenings in a great many applications, notably the assembly of rigid materials, and can withstand up to 1000 opening/closing cycles.
