Description:

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.

This product is also available in some widths with a fabricator splice which is sometimes called a functional splice. This consists of the Dual Lock adhesive and/or the adhesive side of the liner being spliced, thus providing product and liner continuity on the roll. These products are designated with a FS suffix, after the SJ product number.

This product is available in some widths with a colored 3M™ Scotchmate™ Reclosable Fastener loop splice. The Scotchmate reclosable fastener loop engaged to the Dual Lock reclosable fastener provides for a strong splice allowing the product to be pulled through automated converter equipment. These products are designated with a SM suffix after the SJ product number.

A version suitable for use in clean room conditions is designated with a V suffix after the SJ product number. This product is vacuumed to remove particles and surface contaminants before being sealed in plastic bag to reduce the chance for contamination before use.

These Dual Lock reclosable fasteners can be mated in the following combinations of increasing closure strength: Type 170 to Type 250, Type 250 to Type 250, Type 170 to Type 400 and Type 250 to Type 400. In some cases mating with 3M™ Scotchmate™ Reclosable Fasteners Loop provides a quick grab - low engagement force with a high closure strength, but reduced cycle life.
