Screen Sanding AdvantageAbrasives made with 3M™ Cloth Roll 481W are best suited for metal sanding and finishing thanks to its durability and fast cutting abrasive material. Its heavy, screen cloth backing provides excellent durability and can conform to the shape of contoured parts for consistent finishing. The abrasive side features closed coat construction for aggressive sanding and a distinct black color helps to easily differentiate it from other minerals.

Silicon Carbide AbrasivesThis cloth uses silicon carbide, which is a popular choice among industrial professionals because of its fast cut-rate and smooth finish. This synthetic mineral is very hard and fractures easily, resulting in freshly exposed sharp edges that cut extra fast and produce a consistent and professional-looking finish. Silicon carbide products are commonly used for low-pressure applications such as cleaning and finishing on wood and metal. While it wears faster than aluminum oxide, it produces a superior finish.

Waterproof and Heat ResistantThis cloth also uses a resin bonding which is 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 wood. This also allows for faster sanding and a higher cut-rate. Closed coat construction features a dense spread of abrasive mineral across the surface of the cloth. This design cuts fast and provides a consistent finish. The waterproof backing also enables the user to rinse areas of the workpiece and the cloth during use to prevent dust and debris from clogging the points of the abrasive, while at the same time producing a faster cut.
