3M 7000051890 Loop Fastener Roll 1 Inch X 50 Yd Black SJ3523

Product Description

The 3M 7000051890 is a plasticizer-resistant nylon loop fastener roll designed for demanding bonding applications where standard hook-and-loop systems degrade over time. The loop material bonds to mating hook fasteners through a plasticizer-resistant PSA acrylic adhesive backed by a clear 3.5 mil polyethylene film liner. The engaged thickness is 3.1 mm, and the roll measures 1 inch wide by 50 yards long. This fastener is engineered for medium-temperature environments and delivers high high-surface-energy (HSE) bonding performance alongside low low-surface-energy (LSE) capability. Installation is handled by maintenance technicians, assembly workers, and trade professionals working with automotive, industrial, or commercial interior applications.

This loop fastener roll is suited for indoor use across a range of surfaces including paint, bare metal, painted metal, glass, sealed wood, and many plastics. The plasticizer-resistant adhesive system makes it appropriate for environments where contact with plasticizers — common in vinyl and flexible plastic substrates — would otherwise cause adhesive failure. It mates directly with the 3M SJ3522 hook fastener and is available in black to match finished surfaces in visible installations.

Key Features

• Plasticizer-resistant nylon loop construction resists adhesive breakdown in contact with vinyl and flexible plastic substrates
• PSA acrylic adhesive on a clear 3.5 mil polyethylene film liner for clean, consistent application
• 3.1 mm engaged thickness when mated with corresponding hook fastener
• Bonds to paint, bare and painted metal, glass, sealed wood, and many plastics
• Medium-temperature performance rated for indoor use
• Mates with 3M SJ3522 hook fastener for a complete hook-and-loop system

Compatibility

Designed to mate with the 3M SJ3522 hook fastener as part of a complete plasticizer-resistant hook-and-loop fastening system. Suitable for bonding to high-surface-energy and low-surface-energy substrates including paint, bare metal, painted metal, glass, sealed wood, and many plastics in indoor environments.

Installation Notes

Clean and dry the mounting surface thoroughly before applying the adhesive-backed loop strip to ensure maximum bond strength. Peel the polyethylene film liner and apply firm, even pressure across the full length of the strip. Allow adequate dwell time for the PSA acrylic adhesive to achieve full bond strength before loading the fastener. This product is intended for indoor use only — avoid installation in environments with prolonged moisture exposure, direct outdoor weathering, or temperature extremes beyond the medium-temperature rating.
