Product description

Product description

3M Dual Lock TB3550 black hook & loop tape comes in a 1 in width, 10 ft length, uses an acrylic adhesive and is packaged 1 mated strip per inner, 8 bags per case. Can be used to a maximum temperature of +200 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/in. This is an adhesive based hook & loop tape.

From the Manufacturer

Strength in Numbers
One little mushroom won't accomplish much in this world, but pair him up with a few hundred of his friends and he becomes nearly unstoppable. Teamwork, that's the idea behind the design on the 3M Dual Lock Reclosable Fastener TB3550. When joined together, these unique, mushroom-shaped stems combine to interlock with one another, generating five times the closure strength of typical hook and loop fasteners while maintaining the ability to easily peel-apart for quick access.

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. This system can be opened and closed 1,000 times while maintaining 50% of the original tensile strength.

No Drilling, Screwing, Tightening, or Complex Installation
3M Dual Lock TB3550 uses an acrylic adhesive that bonds well to a variety of high medium surface energy materials, including some plastics, metal, glass and painted surfaces. This ensures a quick and easy installation without the use of mechanical attachment processes. 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.

Versatile, Durable and Invisible
There's no limit to the number of uses for 3M Dual Lock fasteners. The stems, mushroom tops, and film backing are constructed of clear polypropylene, and the polyolefin backing resist common solvents and alkaline solutions, making them ideal for a variety of purposes and environments. 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.

Dual Lock Reclosable Fasteners are used extensively in transportation, electronics, business equipment, machinery, medical, and sign and display markets. They are ideal for both indoor and outdoor applications including: attaching signs, cushions, enclosure and access panels, banners, doors, adjustable shelving, vehicle ceiling panels, furniture seats and backs, and much more.
