The hook side features a plasticizer-resistant PSA acrylic adhesive carried on a clear 3.5 mil polyethylene film liner. Engaged thickness measures 3.1 mm. The acrylic adhesive delivers strong bonding to high surface energy (HSE) substrates and acceptable performance on low surface energy (LSE) surfaces. Sold as a 1-inch-wide by 50-yard roll in black, this fastener is intended for professional installation in light industrial, commercial, or OEM assembly applications.\u003c\/p\u003e\u003cp\u003eThis hook fastener is suited for indoor use where substrates include painted metal, bare metal, glass, sealed wood, and many plastics. It is commonly applied in panel attachment, fixture mounting, cable management, and light assembly work where repeated open-and-close cycles are required. Medium temperature performance makes it appropriate for climate-controlled interior environments. It mates with the 3M SJ3523 loop fastener to complete the hook-and-loop system.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePlasticizer-resistant nylon hook construction prevents degradation from plasticizer-rich substrates\u003c\/li\u003e\n\u003cli\u003ePlasticizer-resistant PSA acrylic adhesive on 3.5 mil clear polyethylene film liner\u003c\/li\u003e\n\u003cli\u003e3.1 mm engaged thickness when mated with loop counterpart\u003c\/li\u003e\n\u003cli\u003eBonds to HSE and LSE surfaces including paint, bare and painted metal, glass, sealed wood, and many plastics\u003c\/li\u003e\n\u003cli\u003eMates with 3M SJ3523 loop fastener for a complete hook-and-loop assembly\u003c\/li\u003e\n\u003cli\u003eDesigned for indoor, medium-temperature applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to mate with the 3M SJ3523 plasticizer-resistant loop fastener as part of the SJ3522\/SJ3523 hook-and-loop system for indoor mechanical attachment applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSurface preparation is critical before applying the adhesive-backed hook strip — clean and dry the substrate thoroughly to remove oils, dust, and contaminants prior to bonding. Apply firm, even pressure across the full length of the strip to ensure full adhesive contact. Allow adequate dwell time at room temperature before loading the joint. This product is intended for indoor use only; do not expose to outdoor weathering, standing moisture, or temperature extremes beyond medium-range conditions.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Type\u003c\/strong\u003e: Hook (mates with SJ3523 loop)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Plasticizer-resistant nylon hook, acrylic PSA adhesive, polyethylene film liner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLiner Thickness\u003c\/strong\u003e: 3.5 mil polyethylene film\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngaged Thickness\u003c\/strong\u003e: 3.1 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 50 yards\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSurface Energy Compatibility\u003c\/strong\u003e: High HSE, Low LSE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication Environment\u003c\/strong\u003e: Indoor use only\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Performance\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Roll\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.59 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7000051889\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343089926450,"sku":"7000051889","price":823.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310518257.jpg?v=1782016286","url":"https:\/\/voomisupply.com\/products\/3m-7000051889-hook-fastener-1in-x-50yd-black-sj3522","provider":"Voomi Supply","version":"1.0","type":"link"}
