Its acrylic adhesive bonds strongly to metals, glass, and plastics, making it a versatile, reusable solution for professional-grade fastening needs across industries. ## Description 3M SJ3550 Dual Lock 250 Reclosable Fastener is a general-purpose black reclosable fastener with 250 stems per square inch, an engaged thickness of 0.23 inches and a closure life of 1,000. This black fastener has mushroom-shaped stems on a polypropylene carrier which is coated with a white, general-purpose acrylic pressure-sensitive adhesive. Type 250 stem density fasteners can mate to type 170, 250 or 400 fasteners (the higher the combined number the greater the closure strength). Mushroom-shaped stems on one side of the fastener interlock with identically shaped stems on the other side for 5X greater closure strength than hook and loop.Dual lock type 250 fasteners are designed to bond to metals, glass, and medium-to-high surface energy plastics and paint. They can replace conventional fasteners such as screws, clips, rivets, snaps, hook and loop and bolts in many applications where access or repositioning is needed. Used to attach doors, access panels, signs, cushions, wall headliners, display components, city bus light fixtures, ceiling attachment, privacy curtain rails, sunroof trims, and wall panels. Also for POP (point of purchase), trade show exhibition and electronics, and for attaching E-ZPass tags to car windshields.Dual lock only has one type of side; unlike products where there is a separate hook and a loop side; so rolls are typically cut in half and then mated or connected so a 10-foot roll would be used as two 5-foot strips.Please note: Some rolls may have a white liner with a red 3M logo, others may have a clear liner with a copper 3M logo. Country of Origin: United States. Review: Parfait Review: Very strong adhesive. Use it wisely since you may go through your roll fast. It's a little expensive but the quality is high. ## Features - 3M SJ3550 Dual Lock 250 Reclosable Fastener is a general-purpose black reclosable fastener with 250 stems per square inch, an engaged thickness of 0.23 inches and a closure life of 1,000.
