The design of the 3M™ Dual Lock™ hook and loop tape is made of mushroom-shaped stems. When the stems have combined they interlock together, thus generating five times the closure strength of a typical hook and loop fasteners.

When the two strips are pressed together with the stems flex and the mushroom heads slide past each other. When joined, the stem snaps back into its original position, interlocking with the opposing heads. This system can be opened and closed 1000 times before losing 50% of the original tensile strength.

The Dual Lock™ tape uses an acrylic adhesive that bonds well to a variety of materials, including some plastics, metal, glass, and painted surfaces. The quick adhesion ensures easy installation without the use of a mechanical attachment process. The self-adhesive sticks quickly and reaches full strength after 72 hours. Once bonded the interlocked, mushroom-shaped stems may hold as well as screws and rivets, yet separate easily for access.

The 3M tape features an acrylic foam tape protected by a removable liner. This ensures the construction allows for better contact with surfaces having a slight texture or surface irregularities.
