3M™ 2104 All Purpose Abrasive Sheet, 11 in L x 9 in W, 180 Grit, Very Fine Grade, Aluminum Oxide Abrasive, Paper Backing

3M™ paper 210N is a general purpose abrasive sanding paper constructed on a light, A-weight paper backing and features an open coat construction to help prevent loading. The aluminum oxide abrasive and lightweight backing make this sheet an ideal product for sanding applications such as paint prep, wood sanding, sealer sanding and solid surface finishing. Our 3M™ paper sheet 210N is best suited for hand sanding and finishing due to its exceptional conformability and fast cutting abrasive material. Its A-weight paper backing can be easily cut and folded to fit any workpiece or hand tool and distinct brown color to easily differentiate it from other grits and grains. 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 woodworking. Sanding paper cuts better and lasts longer when dust isn't clogging the cutting surface of the abrasives. Open coat construction means the abrasive grains are placed with space between them to help evacuate sawdust and other sanding debris and avoid clogging the cutting edge of the grains. This allows the sheet to continue cutting even when sanding softwoods, paints and other materials that would, otherwise, clog the grain and hinder sanding ability. Additionally, the open coat feature provides a more aggressive cut than a comparable closed coat abrasive of the same grade. All of this adds up to increased productivity and reduced material consumption.
