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 energy 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 bonding strength over time. SJ3550 has 40 stems / cm² with a 5.8 mm engaged thickness.
