3M Dual Lock SJ3870

Bonding on a wide range of materials. The flexible 3M Dual Lock fastener consists of a polyolefin backing with small mushroom heads that create a stable, yet re-attachable connection when pressed together (audibly). Three different mushroom head densities can be combined to produce varying holding strengths, depending on the requirement. The SJ387 product family, equipped with a high-performance modified acrylic adhesive, is suitable for bonding a wide variety of materials, such as high and low-energy plastics, metals, and many powder coatings.
