Product Details

3M™ Dual Lock™ Reclosable Fastener Blister IPC SJ387B Black

Strength

The design of the 3M™ Dual Lock™ SJ387B 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.

The SJ387B hook and loop tape contains 40 mushroom-shaped stems per cm² (250 per square inch). When the two strips are pressed together the tape is only 6.1 mm thick. 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.

No drilling, screwing, tightening, or complex installation

The Dual Lock™ tape uses a modified acrylic adhesive that bonds well to a variety of materials, including some plastics, metal, glass, and painted surfaces with very little preparation needed. The quick adhesion ensures easy installation without the use of a mechanical attachment process. Once bonded the interlocked, mushroom-shaped stems may hold as well as screws and rivets, yet separate easily for access.

The 3M SJ387B 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.

Versatile, durable and invisible

There's no limit to the number of uses for this tape, with the stems, mushroom tops, and a red film backing. Temperatures between -29 °C and 82 °C will have minimal impact on the performance of this hook and loop tape.
