The roll measures 2.75 inches wide by 45 yards long and features an open-coat aluminum oxide abrasive bonded to a C-weight paper backing. Aluminum oxide is a hard, sharp, durable abrasive that resists heat and performs well at high speeds. The PSA backing bonds firmly to smooth backing pads without requiring mechanical fasteners, making roll changes straightforward when the abrasive is fully worn. This roll is suited for production and job-site environments where a single grit is used until the abrasive is spent.\u003c\/p\u003e\n\u003cp\u003eThis PSA roll is used in woodworking, metal fabrication, auto body, and general finishing applications where 180 grit is appropriate for fine material removal and surface prep. The open-coat construction resists loading, which extends usable life when working softer materials like wood or painted surfaces. The C-weight paper backing conforms well to flat surfaces and provides consistent pressure distribution, making it a practical choice for hand-block sanding or machine-mounted backing pads. It is commonly used by finish carpenters, auto body technicians, and general fabricators.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e180 grit aluminum oxide abrasive for fine material removal and surface finishing\u003c\/li\u003e\n  \u003cli\u003eOpen-coat construction resists loading on wood, paint, and soft materials\u003c\/li\u003e\n  \u003cli\u003ePSA backing bonds securely to smooth backing pads without additional fasteners\u003c\/li\u003e\n  \u003cli\u003eC-weight paper backing delivers consistent pressure across flat work surfaces\u003c\/li\u003e\n  \u003cli\u003e45-yard roll length reduces changeout frequency in production settings\u003c\/li\u003e\n  \u003cli\u003eSingle-use PSA adhesive — not repositionable after initial application\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with smooth-surface PSA backing pads sized for 2.75-inch wide abrasive rolls.

Peel and apply with firm, even hand pressure to eliminate air pockets. Once applied, the PSA adhesive cannot be repositioned, so align the abrasive carefully before contact. Replace the abrasive when the grit is fully worn rather than attempting to remove and reuse it.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 45 yards\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 180\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Type\u003c\/strong\u003e: Open Coat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Type\u003c\/strong\u003e: C Weight Paper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: PSA (Pressure-Sensitive Adhesive)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShipping Weight\u003c\/strong\u003e: 0.371 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 7100371969\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51524756963634,"sku":"7100371969","price":76.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd6fa02e6e0639d5bad92faf624c7101.jpg?v=1785456967","url":"https:\/\/voomisupply.com\/products\/3m-7100371969-sandpaper-roll-180-grit-2-3-4-in-x-45-yd","provider":"Voomi Supply","version":"1.0","type":"link"}
