Durable, Waterproof Abrasive PaperOur 3M™ Wetordry™ Paper Roll 413Q is best suited for metal sanding and finishing thanks to its versatility and fast cutting abrasive material. Its flexible, A-weight paper backing provides smooth operation and durability and can conform to the shape of contoured parts for consistent finishing.Silicon Carbide GrainThe silicon carbide abrasive used in 3M™ Wetordry™ Paper Roll 413Q is popular among industrial professionals because of its fast cut-rate and smooth finish. This mineral is very hard but 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 cleaning and finishing on paint and metal.Waterproof and Heat ResistantThis paper also features a resin bonding specially designed to resist thermal and chemical deterioration, which can occur during sanding. This bond is very tough and excellent for precision work on hard and soft surfaces. This also allows for faster sanding and a higher cut rate. The waterproof coating enables the user to rinse areas of the workpiece and the paper during use to prevent dust and debris from clogging the points of the abrasive, while producing a faster cut at the same time.More Effective Sanding for More Effective OperationsWe put plenty of science behind our 3M™ Wetordry™ Paper Roll 413Q to make the entire sanding process easier. From its durability and heat resistance to its very fast cutting abrasive to its conformability to a variety of surfaces, it's another way that 3M applies science to the lives of auto body professionals, and helps you get the most from your operations.
