Built on a C-weight paper backing, the disc uses a closed-coat ceramic abrasive at 80 grit to deliver fast material removal with a consistently smooth finish. Ceramic abrasive self-sharpens during use, which sustains cut rate longer than aluminum oxide or zirconia alternatives and keeps surface temperatures lower — an important factor when working on heat-sensitive metals, plastics, and composites. Sold in packs of 50, these discs are a practical stock item for body shops, fabrication facilities, and finishing contractors.\u003c\/p\u003e\n\u003cp\u003eThese discs are designed for surface preparation tasks including paint stripping, coating removal, and scuff work before priming or bonding. The 5-inch diameter and PSA mount make them compatible with standard 5-inch random orbital and DA sanders equipped with a hook-and-loop or PSA backup pad. Closed-coat construction — meaning abrasive grain covers the full disc face — provides more uniform scratch patterns and faster stock removal compared to open-coat alternatives. Suitable surfaces include paint, plastic, composites, gelcoat, fiberglass, and carbon steel.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive self-sharpens during use for sustained cut rate and cooler surface temperatures\u003c\/li\u003e\n  \u003cli\u003eClosed-coat grain coverage delivers a smoother finish and faster material removal than open-coat discs\u003c\/li\u003e\n  \u003cli\u003eC-weight paper backing provides a flat, conformable surface for consistent pressure across the workpiece\u003c\/li\u003e\n  \u003cli\u003e80 grit rating suited for aggressive paint and coating removal while leaving a workable scratch profile\u003c\/li\u003e\n  \u003cli\u003ePSA mount for quick disc changes on compatible DA and random orbital sanders\u003c\/li\u003e\n  \u003cli\u003ePack of 50 discs supports high-volume production and shop environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible surfaces and substrates include paint, plastic, composites, gelcoat, fiberglass, and carbon steel.

Press the PSA disc firmly onto a clean, dry backup pad to ensure full adhesive contact before starting the tool. Inspect the disc for tears or loading before each use and replace immediately if damaged. Proper backup pad selection — matching diameter and hardness to the application — is essential for consistent results and operator safety.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoat Type\u003c\/strong\u003e: Closed Coat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\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\u003eSeries\u003c\/strong\u003e: 321U\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Configuration\u003c\/strong\u003e: NH (No Hole)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity per Pack\u003c\/strong\u003e: 50\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: 7100199698\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51525332304178,"sku":"7100199698","price":53.53,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bac912f26cd51243ffaa600cc3f84ed9.jpg?v=1785470808","url":"https:\/\/voomisupply.com\/products\/3m-7100199698-psa-sanding-disc-80-grit-5-inches-50-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
