3M™ Dual Lock™ Reclosable Fastener SJ3551 has a high temperature performance ranging from -30 °C to 70 °C long-term (+95 °C short-term) and can be used indoors and outdoors. Our reclosable fastener is for use with metals (aluminium, stainless steel), glass and high surface energy plastics (acrylic, polycarbonate, ABS), and can be opened and closed 1000 times before losing 50% of its tensile strength. 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. It has 62 mushroom shaped stems / cm² with a 5.8 mm engaged thickness.

3M™ Dual Lock™ Reclosable Fastener SJ3551 solves attachment issues without the use of special tools or complicated, mechanical fastening systems. Our 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. SJ3551 has 62 mushroom shaped stems / cm² (400 per square inch) with a 5.8 mm engaged thickness.
