3M™ Dual Lock™ Reclosable Fastening Systems

3M™ Dual Lock™ Reclosable Fastening Systems 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.

When the Dual Lock™ mushroom-shaped stems interlock, tensile strength is high enough to replace mechanical fasteners in many applications, yet you can readily open and close Dual Lock fasteners hundreds of times. 3M™ Dual Lock™ Reclosable Fastening Systems have been used extensively in transportation, electronics, business equipment, machinery, medical devices as well as in sign and display markets.

3M™ DUAL LOCK™ RECLOSABLE FASTENERS: 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 products construction is especially suited for outdoor applications, where elevated temperatures are experienced or the potential for direct exposure to sunlight or ultraviolet light may occur.

3M™ DUAL LOCK™ LOW PROFILE RECLOSABLE FASTENERS: The Dual Lock low profile reclosable fastener is thinner allowing it to be more flexible than similar reclosable fasteners. The Dual Lock low profile reclosable fastener SJ4570 is a clear fastener offering transparent properties to allow color and patterns to visibly show through giving the
fastener an almost invisible appearance. The Dual Lock low profile reclosable fasteners offer intermediate strength between regular 3M™ Dual Lock™ and 3M™ Scotchmate™ Reclosable Fasteners, with all of the advantages of a self-mating product.
