## Summary description

3M Dual Lock SJ3870 is a reclosable fastener tape supplied as a single 25 mm wide by 1000 mm long piece. It provides a strong interlocking closure suitable for removable panel mounting, cable management, signage and light fixtures. The tape attaches to smooth surfaces and offers repeated opening and closing while maintaining holding strength for practical temporary or semi-permanent applications.

## Long description

3M Dual Lock SJ3870 reclosable fastener tape is a single-piece fastening solution measuring 25 mm in width and 1000 mm in length. The tape features interlocking mushroom-shaped stems that create a firm, reclosable connection between two surfaces. Designed for use on smooth substrates, this tape is suitable for removable panel mounting, temporary fixtures, signage, and cable management where repeated opening and closing is required without significant loss of holding strength.
Advantages
The Dual Lock construction provides consistent, high-shear strength and vibration resistance while allowing repeated reclosures. Its pressure-sensitive adhesive backing enables quick application to many clean, smooth surfaces without mechanical fasteners. The tape's slim profile and flexible backing help it conform to slightly curved surfaces, and its durable interlock mechanism maintains secure attachment in everyday indoor environments.
Suitable for
 Removable panel mounting and access panels
 Signage and display attachment
 Cable routing clips and lightweight fixtures
 Mounting lightweight electrical components and sensors
 Temporary or semi-permanent assemblies requiring repeat access
Key specifications
 Width: 25 mm
 Length: 1000 mm (single piece)
 Fastening type: Reclosable interlocking fastener (mushroom-shaped stems)
 Backing: Flexible tape with pressure-sensitive adhesive
 Suitable surfaces: Smooth, clean substrates (indoor use recommended)
 Performance: Reclosable with maintained holding strength over multiple cycles
How to use
Prepare both bonding surfaces by cleaning with isopropyl alcohol or a suitable solvent to remove dust, oils and release agents; allow surfaces to dry. Cut the Dual Lock tape to the required length, peel off the liner and press the adhesive side firmly onto the first surface. Repeat for the mating piece on the opposing substrate, ensuring alignment. Apply firm pressure across the tape to obtain a secure bond; allow adhesive to develop according to ambient temperature conditions before placing load on the assembly. For best results, avoid immediate heavy loads and allow full adhesion time.
Usage recommendations
For reliable performance, use on clean, non-porous surfaces and avoid application to freshly painted or loosely adhered coatings. Store the tape in a cool, dry place away from direct sunlight. When used for repeated access panels, distribute fastener length or use multiple strips to share the load and reduce peel forces on the adhesive.
