Built on the 401Q platform, it uses silicon carbide mineral bonded to an A-weight waterproof paper backing. Silicon carbide cuts faster than aluminum oxide and leaves a smoother scratch pattern, making it well suited for high-grit finishing stages. At 1500 grit, this disc is intended for final surface prep, paint leveling, and pre-polish work. Licensed tradespeople and finishing technicians reach for this disc when a clean, uniform scratch pattern is required before compounding or buffing.\u003c\/p\u003e\u003cp\u003eThis disc is used in both wet and dry sanding applications across automotive refinishing, marine gel coat finishing, metal fabrication, and wood finishing. The waterproof backing allows water or lubricant to be used during sanding, which reduces loading and extends disc life. It is equally suited for hand sanding blocks and orbital or random-orbit machine sanders. Typical use cases include leveling primer, smoothing paint between coats, and preparing gel coat for polishing compounds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSilicon carbide mineral cuts faster than aluminum oxide and produces a finer finish at equivalent grit levels\u003c\/li\u003e\n\u003cli\u003eA-weight waterproof paper backing supports both wet and dry sanding without delaminating\u003c\/li\u003e\n\u003cli\u003eWaterproof construction reduces loading and extends disc life in wet applications\u003c\/li\u003e\n\u003cli\u003e1500 grit rating suited for paint leveling, primer finishing, and pre-polish surface prep\u003c\/li\u003e\n\u003cli\u003eCompatible with hand sanding and machine sanding applications\u003c\/li\u003e\n\u003cli\u003eSuitable for use on paint, primer, gel coat, metal, and wood substrates\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on 12-inch backing pads for hand or machine sanding applications involving paint, primer, gel coat, metal, and wood surfaces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis disc is installed and removed by finishing technicians or abrasives users — no licensed trade certification is required, but proper PPE including eye protection and a dust mask or respirator should be worn. When sanding wet, ensure adequate ventilation and avoid pooling water near electrical equipment. Inspect the disc before each use and discard if the backing shows tears, delamination, or mineral loss. Do not exceed the speed rating of the backing pad or sander being used.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 1500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Mineral\u003c\/strong\u003e: Silicon Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Weight\u003c\/strong\u003e: A-Weight Paper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Type\u003c\/strong\u003e: Waterproof\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication Type\u003c\/strong\u003e: Wet or Dry\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 7.381 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 12.63 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 250\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 051141279218\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: 7000045221\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344328065330,"sku":"7000045221","price":1373.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310532839.jpg?v=1782033398","url":"https:\/\/voomisupply.com\/products\/3m-7000045221-abrasive-disc-1500-grit-12-inch-wet-or-dry","provider":"Voomi Supply","version":"1.0","type":"link"}
