Product Description 3M™ Dual Lock™ Reclosable Fasteners offer advanced closure alternatives to
zippers, screws, snaps, hooks, bolts and more. They offer greater design flexibility,
faster product assembly, smoother and cleaner exterior surfaces and improved product
performance in many applications. The fasteners consist of continuous polyolefin
strips with polyolefin stems having a mushroom shaped top. The mushroom heads
allow the fasteners to easily slide over each other allowing positioning of parts before
they are snapped together creating a firm fastening attachment. Simply peel the pieces
apart by hand to disengage.
The clear acrylic adhesive combined with the clear backing allows for the substrate
color to show through the fastener. The acrylic adhesive is well suited for applications
exposed to high temperatures, humidity or for high surface energy materials.
This product construction is especially suited for outdoor applications, where elevated
temperatures are experienced or the potential for direct exposure to sunlight or ultra-
violet light may ur. Suggested combinations of mated fasteners are Type 170 to
Type 250, Type 170 to Type 400, Type 250 to Type 250, Type 250 to Type 400, or for
a quick grab attachment with high strength but limited cycle life any of the Dual Lock
products can be mated with 3M™ Scotchmate™ Loop Reclosable Fasteners. See the
technical bulletin on attachments (70-0709-3929-6).
