MATERIALS/FASTENING, JOINING, ASSEMBLY: 3MTM’s ScotchmateTM reclosable fasteners SJ3546/SJ3547 feature hook-and-loop technology for repeated opening and closing with reliable results. The fasteners are designed with tiny, stiff hooks on one side and pliable loops on the reverse side. They are ideal for attaching cushioning in helmets, luggage and seating, curtains on refrigerated displays, removable signs and graphics for POP and trade show booths, truck tonneau covers, access panels, decorative trim and much more. The combination of a flexible backing and adhesive provides conformability to complex contours. The reclosable fasteners’ acrylic adhesive backing bonds on contact to many materials, providing excellent stress resistance, superior high-temperature performance and shear strength, even with repeated pressure to the mating sides. The adhesive bonding system eliminates the need for screws and metal closures in many reclosable applications, and offers reliable performance for indoor and outdoor uses and in high heat and humility.
