3M™ Cloth Roll 384F is an abrasive sanding roll constructed on a durable, polyester cloth backing that features closed coat construction for consistent sanding action. The aluminum oxide abrasive and waterproof polyester construction make this cloth an ideal product for both wet and dry applications such as surface dimensioning and defect removal. Durable Sanding Cloth 3M™ Cloth Roll 384F is best suited for metal sanding and finishing thanks to its durability and fast cutting abrasive material. Made with a flexible and waterproof polyester backing, this cloth roll provides smooth operation and durability which can conform to the shape of contoured parts for consistent finishing. The abrasive side features a closed coat of aluminum oxide grains to provide a fast cut and a fine finish. Aluminum Oxide Abrasive Aluminum oxide is a popular choice among industrial professionals because of its fast cut-rate and long life. This mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges, whereas traditional natural abrasives dull more quickly. Due to its fast cut-rate, hardness, and strength, it is widely used for sanding and finishing applications. Aluminum oxide is suitable for use on a wide variety of materials in metal and woodworking. Waterproof and Heat Resistant 3M™ Cloth Roll 384F 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 allows for fast sanding and a high cut rate. This makes it excellent for precision work on both hard and soft surfaces. The waterproof polyester backing material enables the belt in a woodworking application to rinse areas of the workpiece and the roll during use to prevent dust and debris from clogging the points of the abrasive, while producing a faster cut and extending the abrasive's life.
