3M 7010518603 | Wetordry 8" OAD 431Q x 1/2" Hole Diameter C Weight 240 Grit Silicon Carbide Paper Disc

3M Wetordry paper disc 431Q features extra-fast cutting silicon carbide on a strong, waterproof paper backing that gives you superior finishing for both wet and dry applications on a variety of substrates.

Used with water, the 3M Wetordry discs enable users to rinse areas of the workpiece and the sheet during use to prevent dust and debris from clogging the points of the abrasive and reduce air-borne dust while producing a faster cut at the same time. These versatile discs are ideal on surfaces that tend to generate a lot of dust, such as paint, primer, and wood; and can also be used dry for finishing metal and gel coats. The adhesive backing provides easy attachment to a random orbital sander.

These disks use silicon carbide, a mineral that is very hard and fractures easily, resulting in freshly exposed sharp edges that cut extra fast and produce a smooth, professional-looking finish. Silicon carbide products are commonly used for low-pressure applications such as paint prep and finishing on wood and metal. While it wears faster than aluminum oxide, it produces a superior finish.

3M Wetordry products are backed with a 3M proprietary durable waterproof paper backing that supports both wet and dry applications. Lighter weight than cloth, and smooth rather than textured, paper backing is preferable for lighter applications such as finishing and paint prep. At the same time, many such applications produce a significant amount of dust, clogging the abrasive points and creating an inferior work environment. These effects can be minimized by sanding with water to rinse dust away from the workpiece and the abrasive surface.

• Versatile disc can be run wet or dry on paint, primer, gel coat, metal, and wood
• Waterproof backing supports wet applications for decreased loading and a faster cut
• Strong C-weight paper backing provides durability for either hand or machine sanding
• Silicon carbide mineral cuts faster than aluminum oxide and produces a smoother finish
• Adhesive backing provides easy attachment to random orbital sander
