3M Scotch SJ3551 Dual Lock 400 Reclosable Fastener is a general-purpose black reclosable fastener with 400
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
Type 400 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 400 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.

Carrier/Backing: polypropylene. Adhesive: acrylic (300 LSE). Release Liner: clear polyolefin film.
