The 3M™ Dual Lock™ Rolls are a range of fastening systems which use interlocking mushroom-shaped stems to join with one another when fastened together to create a seal. This high-quality sealing system comes with a range of rolls with adhesive backs as well as plain backs, which can be stapled or sewn onto any material or surface. All adhesive rolls have a plastic protecting liner in the back of the strip.
Based on your needs the 3M™ Dual Lock™ Rolls differ in their adhesive type (we offer rolls with no backing, rubber adhesive for general uses, and acrylic for high-performance bond) and different types of disengagement strength. Low disengagement strength dual lock rolls will not mate with themselves, whereas most medium, high, and very high rolls will mate normally. Please note that the SJ4570 Dual Lock Low Profile Roll has a medium/high disengagement strength and will mate only with itself.
All adhesive backed 3M™ Dual Lock™ Rolls come with instruction indicating how to best apply and attach the strips, please follow directions for best results. We recommend that surfaces are smooth and clean, free of oil, dirt, and dust particles that could break adhesive bonds. Depending on the disengagement strength and type of adhesive, each Dual Lock™ roll will have a different waiting period for adhesives to bond to a surface before the strips can be pushed together using pressure to interlock the mushroom-shaped stems.
Each type of Dual Lock™ roll will be able to accommodate different types of jobs from tiling to simpler household applications. Please click through to read more about each 3M™ Dual Lock™ Roll and contact our technical helpline for advice on your upcoming project and Dual Lock™ Roll needs.
