3M™ Dual-Lock Reclosable Fastener - Squares SJ-355X

 

Strength

 

The design of the 3M™ Dual Lock™ SJ355X hook and loop tape is made up of mushroom-shaped stems in uniformed squares. When the stems have combined they interlock together, thus generating five times the closure strength of a typical hook and loop fasteners.
The SJ355X hook and loop tape contains 40 mushroom-shaped stems per cm² (250 per square inch). 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 clear acrylic adhesive that bonds well to a variety of materials, including some plastics, metal, glass, and painted surfaces. The squares are backed with a pressure sensitive adhesive. Once bonded the interlocked, mushroom-shaped stems may hold as well as screws and rivets, yet separate easily for access.
The 3M SJ-355X tape features a pressure sensitive acrylic nylon 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 film backing made of polypropylene. The fastener is recommended for low temperatures reaching 50 °C long term (70 °C short term).
