Built on a C-weight waterproof paper backing, it carries a silicon carbide abrasive mineral that produces finer surface finishes than aluminum oxide alternatives. At 8 inches in diameter and 240 grit, this disc targets final-stage material removal and surface prep work. The pressure-sensitive adhesive (PSA) backing mounts directly to compatible random orbital sanders without separate fasteners. Body shops, marine refinishers, woodworkers, and metal fabricators use this disc wherever a controlled, consistent scratch pattern is required before topcoat or final finishing.\u003c\/p\u003e\u003cp\u003eThis disc is suited for both professional shop environments and production-line applications where wet sanding is preferred to reduce loading and extend abrasive life. Substrates include paint, primer, gel coat, bare metal, and wood. Running the disc wet flushes swarf away from the abrasive face, reducing heat buildup and extending cut life. Running it dry on machine sanders delivers firm, consistent stock removal. Either method is supported by the waterproof C-weight paper backing, which resists delamination under wet conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSilicon carbide mineral delivers finer finish quality compared to aluminum oxide on paint, primer, and gel coat\u003c\/li\u003e\n\u003cli\u003eWaterproof C-weight paper backing supports wet sanding to reduce loading and improve cut rate\u003c\/li\u003e\n\u003cli\u003ePSA backing mounts quickly to random orbital sander platens with no mechanical fasteners\u003c\/li\u003e\n\u003cli\u003eRated for both hand sanding and machine sanding applications\u003c\/li\u003e\n\u003cli\u003e240 grit targets finish prep and inter-coat scuffing on a variety of substrates\u003c\/li\u003e\n\u003cli\u003eVersatile substrate compatibility: paint, primer, gel coat, metal, and wood\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with PSA-style random orbital sander platens accepting 8-inch discs.

Power down and unplug the sander before disc changes. When running wet, verify the sander is rated for wet use before operating near water. Dispose of used discs in accordance with local regulations if sanding materials containing lead paint or other hazardous coatings.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 240\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Mineral\u003c\/strong\u003e: Silicon Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Type\u003c\/strong\u003e: C-Weight Waterproof Paper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment\u003c\/strong\u003e: Pressure-Sensitive Adhesive (PSA)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Wet or Dry\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 11.3 x 8.9 x 9.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051144213665\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: 7010295206\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344069525810,"sku":"7010295206","price":2633.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310534213.jpg?v=1782028246","url":"https:\/\/voomisupply.com\/products\/3m-7010295206-wetordry-431q-8-inch-240-grit-psa-disc","provider":"Voomi Supply","version":"1.0","type":"link"}
