3M 7000001960 Dual Lock Reclosable Fastener SJ3560 Clear

Product Description

The 3M 7000001960 is the Dual Lock Reclosable Fastener SJ3560, a pressure-sensitive fastening tape that bonds to itself when pressed together and releases cleanly when pulled apart. It features a clear acrylic adhesive backing on a clear polypropylene mushroom-stem fastener with 250 stems per square inch and an engaged thickness of 0.23 inches. Rated for up to 220 degrees F, this fastener is built for demanding environments where conventional hook-and-loop solutions fall short. It ships as a 1-inch-wide roll, 50 yards in length, and is sold by the roll.

This fastener is suited for both indoor and outdoor applications across HVAC, electrical, and general trade work. Common uses include securing panels, mounting control components, organizing wire runs, and attaching signage or access covers to metal, glass, and high-surface-energy plastic substrates. Substrates include aluminum, stainless steel, glass, acrylic, polycarbonate, and ABS. The clear construction keeps installations visually clean.

Key Features

• 250 stems per square inch for consistent, repeatable closure strength
• Rated closure life of 1,000 open-and-close cycles
• Maximum temperature rating of 220 degrees F for high-heat environments
• Clear acrylic adhesive with clear polypropylene fastener body for low-profile appearance
• Engaged thickness of 0.23 inches
• Suitable for indoor and outdoor use on metals, glass, and high-surface-energy plastics

Compatibility

Designed for bonding to metals including aluminum and stainless steel, glass, and high-surface-energy plastics such as acrylic, polycarbonate, and ABS. Not recommended for low-surface-energy plastics such as polyethylene or polypropylene substrates without surface preparation.

Installation Notes

Surface preparation is critical — clean and dry all bonding surfaces before applying the adhesive-backed fastener. Apply firm pressure along the full length of the strip to ensure proper adhesive contact. Allow adequate dwell time before loading the joint. No special tools or trade license is required, but follow applicable safety data for adhesive handling in enclosed spaces.
