3M Dual Lock Reclosable Fastener SJ3550 solves attachment issues without the use of special tools or complicated, mechanical fastening systems. Our reclosable fastener uses an acrylic adhesive that bonds well to a variety of high and medium surface ene rgy materials, including some plastics, metal, glass, and painted surfaces. This allows you to attach access doors, panels, signs, display components, and many other frequently opened and closed parts for easy, repeated access with minimal loss of bond ing strength over time. It has 40 mushroom shaped stems / cm2 with a 5.7 mm engaged thickness, a temperature performance ranging from -30 C to 70 C long-term (+95 C short-term), and can be used indoors and outdoors.,Strength in numbers
One little mu shroom 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 of 3M Dual Lock Reclosable Fastener SJ3550. When they’re joined together, the u nique, 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. Our SJ3550 reclosable fastener cont ains 40 mushroom shaped stems / cm2 (250 per square inch). When two pieces 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 he ads with an audible snap that signals the fastener is engaged. This system can be opened and closed 1000 times before losing 50% of the original tensile strength. No drilling, screwing, tightening, or complex installation
SJ3550 uses an acrylic adhesi ve 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 a mechanical attachment process. The adhesive sticks qui ckly and reaches full strength after 72 hours. 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 these fasteners. The stems, mushroom tops, and film backing are constructed of polypropylene, while the polyolefin backing resists common solvents and alkaline solutions, making them ideal for a variety of purposes and environments.
