3M DIAMOND GRADE CONSPICUITY MARK

This versatile 3M™ Wetordry™ PSA Paper Disc 431Q is designed for both wet and dry sanding applications on a variety of surfaces including paint, primer, gel coats, metal, and wood. When used wet, these discs help rinse away dust and debris, preventing clogging, reducing airborne dust, and promoting a faster cut. The waterproof paper backing is lighter than cloth and provides durability for hand or machine sanding. Featuring a silicon carbide abrasive mineral, these discs offer a very hard and easily fracturing abrasive that exposes fresh sharp edges for a smooth finish, ideal for low-pressure applications like paint prep and finishing. The Pressure Sensitive Adhesive (PSA) backing allows for easy and secure attachment to a random orbital sander, suitable for high heat and severe disc sanding applications. Convenient liners prevent contamination of the disc backing before use.
