3M™ Dual Lock™ reclosable fastener TB4575 is a low profile fastener designed for use in a variety of attachment solutions. It features a continuous strip of polyolefin stems with mushroom shaped tops protruding up from the backing. These fasteners can be opened and closed up to 150X before losing 50% of the original tensile strength. Low profile, self mating fastener. The mushroom shaped heads on the 3M™ Dual Lock™ reclosable fastener TB4575 easily slide over each other, allowing for the positioning of parts before they snap together to create a firm fastening attachment. When mated, the fasteners are hidden from view and leave an unbroken surface to help create a smooth, clean appearance. The pressure sensitive acrylic adhesive sticks to metals (aluminum, stainless steel), glass, many plastics (polypropylene, polyethylene, polycarbonate, ABS), powder coated paints and medium to low surface energy materials. After passing the mushroom heads on the opposing mating piece, a stem snaps up into its original position, interlocking with the opposing heads. The audible snap signals the fastener is engaged. The attachment formed may be as effective as screws or rivets, but will peel apart for repositioning. 3M™ Dual Lock™ reclosable fasteners are used extensively in transportation, electronics, business equipment, machinery, medical and sign and display markets. Applications include attaching signs, enclosure panels, banners and furniture seats and backs. Today, designers, manufacturers and consumers expect more options to secure, attach and connect surfaces. 3M™ Dual Lock™ reclosable fasteners offer instant installation and high strength attachment, yet can be opened as easily as zippers. That functional flexibility, as well as superior aesthetics, reduced weight and savings in labor and installation costs, make these innovative fasteners a popular and effective solution. 3M™ Dual Lock™ reclosable fastener trial bags provide a simplified, go to selection that has proven successful for most common applications, along with just the right length and quantity for trial run testing.
