3M™ Dual Lock™ Reclosable Fastener SJ3550
Product details
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.
Features
- An acrylic foam tape protected by a removable liner
- Black fastener with 40 mushroom shaped stems / cm² (250 per square inch)
- Pressing two pieces together allows 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 heads with an audible snap that signals the fastener is engaged.
- Thickness: 5.8 mm
- Temperature performance ranging from -30 °C to 70 °C long-term (+95 °C short-term)
- Designed to bond to metals, glass and medium to high surface energy plastics and paint
- Can be used indoors and outdoors.
