3M SJ3541 25,4mm x 45,7m, 3M Dual Lock™ SJ3541 Black Hook & Loop Tape, 25.4mm x 46m

3M™ Dual Lock™ Reclosable Fastener SJ3541, Black 25.4mm x 46m

Strength

The design of the 3M™ Dual Lock™ SJ3541 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 SJ3541 hook and loop tape contains 40 mushroom-shaped stems per cm² (250 per square inch). 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.

No drilling, screwing, tightening, or complex installation

The Dual Lock™ tape uses a conformable foam and 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. Once bonded the interlocked, mushroom-shaped stems may hold as well as screws and rivets, yet separate easily for access.

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 polyolefin backing resists common solvents and chemicals, making them ideal for a variety of purposes and environments. The fastener features good temperature resistance up too 49 °C.

FAQ's

How is hook and loop attached to a product?

There are a number of ways to attach hook and loop to a product. Having a fabric backed hook and loop, it can be sewn into textiles and fabrics. It can be glued to a surface using pressure sensitive adhesives or even applied using a heat activated adhesive.

Does water affect the performance of hook and loop tape?

Hook and Loop tape will not degrade in water and water doesn't affect the holding strength of the tape.
