3M™ Dual Lock™ flexible pressure lock SJ387B
The 3M™ Dual Lock™ flexible pressure lock consists of a polyolefin backing with small mushroom heads that create a strong bond when pressed together (audibly) but can be opened and closed up to 1,000 times. Unlike conventional fastening systems, such as screws or rivets, no holes that impair the optical appearance of the surface are required. SJ387B is equipped with a high-performance, modified acrylate adhesive and is suitable for bondings on a large number of materials, e. g. on high- and low-energy plastics, metals and many powder coatings.
