-
These film discs are designed for machine sanding applications and provide efficient performance when used with appropriate equipment.
3M has designed the Microfinishing PSA Film Disc 366L with advanced features to enhance efficiency and prolong product life. The disc is equipped with an anti-load coating and open coat surface, which effectively minimizes loading and allows for optimal performance. The abrasive is resin-bonded, providing flexibility without compromising durability, ensuring reliable performance even under high heat and pressure conditions.
The polyester film backing of the disc is designed to flex, enabling consistent finishing over contours. It also offers superior tear-resistance compared to similar paper products, making it an ideal choice for high-production environments. The pressure sensitive adhesive (PSA) ensures easy attachment, securely holding the disc in place during use, and can be cleanly removed from the backup pad (sold separately).
The 3M Microfinishing PSA Film Disc 366L features precision, micron-graded aluminum oxide as its abrasive material. This choice of mineral is highly favored by industrial professionals due to its fast cut-rate and long life. The aluminum oxide is a tough and durable abrasive that self-fractures, exposing fresh cutting edges. This characteristic sets it apart from traditional natural abrasives, which tend to dull more quickly. Its fast cut-rate, hardness, and strength make it suitable for a wide range of applications, including grinding, sanding, and finishing in both woodworking and metalworking, including ferrous alloys.
To ensure optimal cutting performance and longevity, the sanding discs are designed with an open coat construction. This means that the abrasive grains are spaced apart, allowing for efficient evacuation of sawdust and other sanding debris. This prevents clogging of the cutting edge of the grains, enabling the discs to cut better and last longer. The load-resistant coating further enhances the disc's ability to continue cutting, even when sanding softwoods, paints, and other materials that would typically clog the disc and hinder sanding ability. Additionally, the open coat feature provides a more aggressive cut compared to a comparable closed coat abrasive of the same grade. These features collectively result in increased productivity and reduced material consumption.
The 3M sanding discs are available in various forms to fit different power tools and disc pads. These high-quality abrasive products come with a pressure sensitive adhesive coating on the backside, allowing for easy attachment to a backup pad or hand pad. They can be cleanly removed, leaving behind an uncontaminated surface for the next sheet or disc, ensuring a seamless sanding experience.
