3M 7010374477 Dual Lock Reclosable Fastener SJ3562 Clear

Product Description

The 3M 7010374477 is the Dual Lock Reclosable Fastener SJ3562, a clear polypropylene interlocking fastener strip with a clear acrylic pressure-sensitive adhesive backing. It delivers 170 mushroom-shaped stems per square inch, producing a firm mechanical closure with an engaged thickness of 0.23 inches. Rated for up to 1,000 open-and-close cycles, this fastener maintains reliable performance across repeated use. The high-temperature rating of 220 degrees F makes it suitable for demanding indoor and outdoor environments where conventional hook-and-loop would degrade. This roll format is commonly installed by HVAC technicians, electricians, and industrial maintenance professionals who need a durable, repositionable fastening solution.

SJ3562 is suited for mounting and securing components to metals including aluminum and stainless steel, glass, and high surface energy plastics such as acrylic, polycarbonate, and ABS. The roll format — 2 inches wide by 50 yards long — allows technicians to cut strips to length on the job, making it a practical fit for panel covers, access doors, junction box lids, equipment labels, and similar applications in both residential and commercial settings.

Key Features

• 170 stems per square inch for firm, consistent mechanical engagement
• Clear polypropylene construction with clear acrylic adhesive backing
• 0.23 inch engaged thickness for low-profile fastening
• Rated for 1,000 open-and-close cycles
• High-temperature performance up to 220 degrees F
• Suitable for indoor and outdoor use

Compatibility

Bonds to metals (aluminum, stainless steel), glass, and high surface energy plastics including acrylic, polycarbonate, and ABS surfaces. Not recommended for low surface energy plastics such as polyethylene or polypropylene substrates.

Installation Notes

Surface preparation is critical — clean all bonding surfaces thoroughly with isopropyl alcohol and allow to dry completely before applying the adhesive backing. Apply firm pressure across the full strip length to ensure full adhesive contact. Allow adequate dwell time before loading the joint. No special tools are required, but a roller applicator improves adhesive transfer on flat surfaces.
