Series Data Sheet

3M™ Dual Lock™ SJ3540 has mushroom shaped heads that snap together. This product is a "Type 250" which means it has approximately 250 stems per square inch. It will "mate" to itself and other Type 250, Type 170 and Type 400 3M™ Dual Lock™ fasteners. When mating to Type 170 there will be less of a grip, while mating to Type 400 will provide a tighter grip. Most applications will work using just Type 250 alone and has the added ease of only having to keep track of one type of Dual Lock. SJ3540 can be identified by the plain white backing (liner) with a dark grey, almost black foam adhesive underneath. The foam has a rubber based adhesive that should only be used for indoor applications and will stick to most surfaces. It is the suggested best option if you are trying to adhere to powdered paint or wood. This adhesive will perform poorly however on car dashboards.
