3M™ Wetordry™ Paper Disc, 431Q, 180 C-weight, 8 in x NH (203.2 mm x NH), Die 800L

The 3M™ Wetordry™ Paper Disc 431Q features extra-fast cutting silicon carbide on a strong, waterproof paper backing that helps you achieve a superior finish in both wet and dry applications on a variety of substrates.

Used with water, the 3M™ Wetordry™ Paper Disc 431Q enables you to rinse areas of the workpiece sheets during use to help prevent dust and debris from clogging the points of the abrasive. The disc also helps reduce airborne dust, while producing a faster cut at the same time. These versatile discs are ideal for surfaces that tend to generate a lot of dust, such as paint, primer, and wood. They can also be used dry for finishing metal and gel coats. The adhesive backing provides easy attachment to a random orbital sander. Silicon carbide mineral 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.
