3M™ Dual Lock™ Twin Packs
Technical Help / Filters3M™ 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 offer improved resistance to edge peel which can be provided by recessing the Dual Lock fastener, or by rounding the corners. In some exceptional cases (contamination by mould release, rough or porous surfaces etc.) it may be necessary to sand or abrade the surface or use an adhesive primer to optimise bond performance.
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’re 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.
