3M 7000029690 Dual Lock Fastener SJ4570 Clear 6in X 50yd

Product Description

The 3M 7000029690 is a Dual Lock reclosable fastener sold as a continuous roll measuring 6 inches wide by 50 yards long. It features a low surface energy (LSE) acrylic adhesive bonded to the back of a clear polypropylene mushroom-stem strip. The engaged thickness when two mating strips are closed is 0.10 inches, producing a low-profile assembly that works well in tight tolerances. Rated for up to 100 closure cycles, this fastener is engineered for indoor applications requiring a reliable, tool-free mechanical bond. Temperature resistance reaches 158 degrees F, making it suitable for low to medium temperature environments. The roll weighs 12 pounds and ships as a single unit.

This fastener is used in interior panel attachment, cable management, signage mounting, and light-duty component securing across commercial and industrial settings. It adheres directly to metals such as aluminum and stainless steel, glass, and a wide range of plastics including polypropylene, polyethylene, polycarbonate, and ABS. It also bonds to powder-coated paint surfaces and other medium to low surface energy substrates. It is not intended for outdoor exposure, high-temperature environments above 158 degrees F, or very high surface energy materials where a PSA-only bond would be insufficient.

Key Features

• Low profile design with 0.10 inch engaged thickness for space-constrained installations
• Rated for 100 open-and-close cycles, providing long service life in repeated-access applications
• Low surface energy acrylic adhesive bonds to LSE plastics, metals, glass, and powder-coated surfaces
• Clear polypropylene construction keeps fastener visually unobtrusive on transparent or finished surfaces
• Temperature resistance to 158 degrees F for low to medium thermal environments
• Continuous 6 inch wide by 50 yard roll allows field cutting to any required length

Compatibility

Designed for bonding to metals (aluminum, stainless steel), glass, polypropylene, polyethylene, polycarbonate, ABS plastics, powder-coated paints, and medium to low surface energy materials. For indoor use only.

Installation Notes

Surface preparation is critical for LSE adhesive systems — clean and degrease all substrates thoroughly before application. Apply firm, even pressure across the full strip after positioning to ensure full adhesive contact. Allow adequate dwell time per standard PSA bonding practice before loading the joint. This product is intended for indoor use; do not expose to outdoor conditions, UV, or temperatures exceeding 158 degrees F.
