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.

Please note SJ 4570 only mates to itself - and we do not recommend SJ 3552 mates to itself.
