Series Data Sheet

3M™ Dual Lock™ SJ3870 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. It has black stems with 3M's black modified Very High Bond (VHB™) adhesive backing. SJ3870 adhesive bonds well to plastics and can deal with outdoor conditions. The modified acrylic adhesive provides the "quick stick" quality of rubber adhesives and the durability and versatility of acrylic adhesives.
