3M™ Dual Lock™ Twin Packs contain two rolls of high-quality, mushroom-type reclosable fastening systems. All twin packs mate with themselves.

3M SJ354D™ and 3M™ SJ355D are known for their improved resistance to edge peel – this can be achieved by recessing the Dual Lock fastener as well as by rounding the corners. There may be some unusual cases, such as contamination caused by mould or working with surfaces that are porous, where surfaces need to be sanded and primed before the tape is applied.

3M™ SJ355T pressure-sensitive adhesive (PSA) can be used in conjunction with staples or other methods of mechanical attachment to provide additional holding strength, particularly at elevated temperatures or on rough or porous surfaces.

3M™ SJ356D is a clear, pressure-sensitive very high bond (VHB™) acrylic adhesive which is UV resistant and plasticiser resistant.

Whether you are looking for a general-purpose dual lock tape, or a dual lock system suitable for specialised applications such as aircraft, automotive or electronic – our range is sure to have the product for you.
