3M™ Dual Lock™ Reclosable Fasteners SJ3550, SJ3551 and SJ3552 consist of continuous
strips of polyolefin stems with a mushroom shaped top protruding up from the backing.
There are three types (170, 250 and 400) of these fasteners referring to the approximate
number of stems per square inch.
These fasteners have a 37 mil white conformable acrylic foam adhesive providing good
contact with substrates having a slight texture or surface irregularities. The adhesive is
protected with a clear silicone treated liner allowing easy removal from the adhesive.
