Technical Help / Filters

3M™ 5 Metre Dual Lock™ Rolls are a high-quality re-closable fastening system where mushroom shaped stems interlock with one another when pressed together. Available in 25mm black or clear, plain backed or with rubber or acrylic self-adhesive backing.

 

3M™ SJ3540 is a general-purpose pressure sensitive rubber adhesive suitable that bonds to most surfaces. This 25mm x 5m roll mates well with itself.

 

3M™ SJ3550 and 3M™ SJ3551 are pressure sensitive, very high bond (VHB™) acrylic adhesives that offer high performance for aircraft, automotive, business equipment, and electronics applications. Both variations resist harsh wet and dry conditions, as well as hot and cold cycles.

 

3M™ SJ3560 is a clear, pressure sensitive, very high bond (VHB™) acrylic adhesive with UV resistant properties and is plasticiser resistant.

 

3M™ SJ4570 is a pressure sensitive adhesive (PSA) attachment that provides reliable bonding to a wide variety of materials, such as metals, acrylic, glass, polycarbonate, fibreglass, polystyrene, and powder coated paints. Please note SJ 4570 only mates to itself - and we do not recommend SJ 3552 mates to itself.

 

Each of these rolls provides 1000+ closures per roll with a disengagement strength of 250.
