3M 7010312616 Dual Lock Reclosable Fastener SJ3542 Black

Product Description

The 3M 7010312616 is a roll of Dual Lock Reclosable Fastener SJ3542, a pressure-sensitive, interlocking fastener system designed for tool-free attachment and repeated opening and closing. The fastener features a rubber-based adhesive backing bonded to a black polypropylene mushroom-stem surface. At 400 stems per square inch, it delivers reliable closure with an engaged thickness of 0.23 inches. Rated for up to 1,000 closure cycles, this fastener is suited for assembly applications where components must be accessed and reattached regularly. It is intended for indoor use only and carries a maximum temperature resistance of 120 degrees F.

This fastener is used in light industrial, commercial, and trade assembly applications where screws, rivets, or conventional hook-and-loop are impractical. Common uses include panel mounting, component securing, and surface attachment on equipment enclosures, display fixtures, and control panels. It adheres well to a range of substrates including acrylic, polycarbonate, ABS, powder-coated paints, and low-surface-energy materials such as polypropylene and polyethylene. Each roll measures 6 inches wide by 50 yards in length, providing a continuous supply for high-volume or large-format applications.

Key Features

• 400 stems per square inch for consistent, repeatable closure force
• 0.23-inch engaged thickness when mated face-to-face
• Rated for 1,000 open-and-close cycles
• Rubber-based adhesive backing for broad substrate compatibility
• Black polypropylene construction rated to 120 degrees F
• Indoor use only; adheres to low-surface-energy plastics including polypropylene and polyethylene

Compatibility

Compatible with acrylic, polycarbonate, ABS, powder-coated painted surfaces, polypropylene, and polyethylene substrates. Intended for indoor applications only.

Installation Notes

Surface preparation is critical before application — clean bonding surfaces thoroughly to remove oils, dust, and debris to achieve full adhesive contact. Apply firm, even pressure across the full tape surface after placement to ensure proper adhesion. Allow adequate dwell time before loading the fastener joint as specified by standard pressure-sensitive adhesive practice. Do not use in outdoor, high-humidity, or elevated-temperature environments exceeding the rated maximum.
