Can be used to a maximum temperature of +200 deg F. These products are generally considered "hook & loop" products. While the traditional system is that of a hook and a loop some of these products also use an interlocking mushroom like head. This particular 3M item is the mushroom hook side with a density of 250 stems/in2. This is an adhesive based hook & loop tape. The adhesive sticks quickly and reaches full strength after 72 hours. Once bonded the interlocked, mushroom-shaped stems provide an attachment that holds as well as screws or rivets, yet separates easily for access. This system can be opened and closed 1,000 times while maintaining 50% of the original tensile strength. The fastener is recommended for use at temperatures ranging from -20°F/-29°C to 200°F/93"C. Hidden from view when attached, these fasteners provide a clean, unbroken surface, and stay strong through more than 1,000 open-close cycles. 3M Dual Lock TB3550 Reclosable Fastener contains approximately 250 mushroom-shaped head stems per square inch. When two pieces of Dual Lock are pressed together the stems flex and the mushroom heads slide past each other. After mating, the stem snaps back into its original position, interlocking with the opposing heads with an audible snap that signals the fastener is engaged. Versatile, Durable and Invisible
