3M™ Microfinishing PSA Film Disc Roll 366L, 30 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 features 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, and more. 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, which can occur when dust and debris clog the cutting surface of the abrasive. The open coat construction also allows for better evacuation of sawdust and sanding debris, preventing clogging and ensuring a consistent cutting performance. The abrasive itself is resin-bonded, providing flexibility without sacrificing durability. This means that the discs can withstand high heat and pressure, making them suitable for demanding applications. The polyester film backing adds to the durability of the discs, offering greater tear-resistance compared to traditional paper products. This makes them ideal for use in high-production environments where longevity is important. The pressure sensitive adhesive (PSA) coating on the backside of the discs allows for easy attachment to a backup pad or hand pad. It securely holds the disc in place during use, ensuring a stable and reliable sanding experience. When it's time to remove the disc, it cleanly detaches from the backup pad, leaving behind an uncontaminated surface for the next sheet or disc. These discs are designed for use with orbital and random orbital sanders, providing versatility and compatibility with various power tools. They are available in a range of micron grades, allowing for multi-step sanding and finishing processes. Additionally, there is a dust-free option available, further enhancing the cleanliness and efficiency of the sanding operation. In summary, the 3M Microfinishing PSA Film Disc Roll 366L is a top-quality abrasive product that offers fast cut-rate, uniform finish, and long life. Its premium aluminum oxide abrasive, durable polyester film backing, and anti-load coating make it a reliable choice for a wide range of sanding and finishing applications.
