3M™ Microfinishing PSA Film Disc Roll 366L, 50 Mic 3MIL, Type D, 5 in x NH, Die 500X, 125 Discs/Roll, 4 Rolls/Case

The 3M Microfinishing PSA Film Disc Roll 366L is a versatile and high-performance abrasive product designed for sanding and finishing applications. It is made with a premium, micron-graded aluminum oxide abrasive that is bonded to a durable polyester film backing. This combination allows for a fast cut-rate and uniform finish on a wide range of materials including wood, solid surface composites, plastic, fiberglass, paint prep, coating and corrosion removal, primer, e-coat, and metal. One of the key features of these discs is the anti-load coating and open coat surface. This design helps to increase efficiency and product life by minimizing loading. The open coat construction also allows for better evacuation of sawdust and other sanding debris, preventing clogging of the cutting edge of the grains. This means that the discs cut better and last longer, resulting in increased productivity and reduced material consumption. The abrasive used in these discs is resin-bonded, providing flexibility without sacrificing durability. This ensures reliable performance even under high heat and pressure. The polyester film backing is designed to flex, allowing for a consistent finish over contours. It also offers greater tear-resistance compared to comparable paper products, making it ideal for high-production environments. The pressure sensitive adhesive (PSA) coating on the backside of the discs provides easy attachment and holds the disc securely in place during use. It also allows for clean removal from the backup pad, leaving an uncontaminated surface for the next sheet or disc. These discs are designed for use with orbital and random orbital sanders, and they come in a range of micron grades and dust-free options for complete multi-step sanding and finishing. The 3M Microfinishing PSA Film Disc Roll 366L features precision, micron-graded aluminum oxide, which is known for its fast cut-rate and long life. This mineral is widely used in grinding applications as well as sanding and finishing applications. It is suitable for a variety of materials in both woodworking and metalworking, including ferrous alloys. Overall, these 3M sanding discs are a reliable and efficient choice for professionals in various industries. They offer a fast cut-rate, uniform finish, and long life, making them a valuable tool for achieving high-quality results.
