3M Stikit Paper Disc Roll 236U, P80 C-weight, 3-1/2 in x NH, Die 350HH, 100 Discs/Roll

The open-coat construction and load-resistant coating help prevent clogging to maximize cut and the useful life of the disc. 3M™ Stikit™ Paper Disc Roll 236U can be used for sanding and finishing on many different surfaces, such as paint, primer, softwood, metal, plastic, hard and soft composites, and fiberglass. Our 3M™ Stikit™ discs are designed to handle a wide range of sanding and finishing needs. These high-quality, coated abrasive products come ready to use with a pressure sensitive adhesive coating on the backside so they conveniently press on to the backup pad, and remove cleanly, leaving an uncontaminated surface for the next disc. The Stikit™ disc should be used in conjunction with our 3M™ Stikit™ backup pad (also called a disc pad and sold separately) that is attached to a disc sander, random orbital sander, or stationary disc sander. 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 in grinding applications in addition to sanding and finishing applications. Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys. 3M™ Stikit™ Paper Discs feature a load-resistant coating that allows the disc to continue cutting even when sanding softwoods, paints, and other materials that would, otherwise, clog the surface of the disc and hinder sanding ability. An open coat means the abrasive grains are spaced slightly apart so that dust can escape rather than loading the cutting edge of the grains, thereby optimizing cut-rate and disc life.
