The 3M™ Microfinishing PSA Film Roll 268L is a fast-cutting abrasive for precise, uniform, close-tolerance finishes. Aluminum oxide is resin-bonded to a 3 mil (0.08), high-strength polyester film backing that provides durability and flexibility for consistent finishing on contoured surfaces. The pressure-sensitive adhesive (PSA) backing enables easy attachment to a backup pad. Use wet or dry.The 3M Microfinishing PSA Film Roll 268L features precision, micron-graded aluminum oxide, resin-bonded to a high-strength polyester film backing to produce a fast cut-rate and precise, uniform finish on wood, solid surface composites, plastic, fibreglass and metals. The film backing offers flexibility without sacrificing durability and reliable performance. To complement the effective abrasive action, the polyester film backing flexes to help achieve a consistent finish over contours and offers greater tear-resistance than comparable paper products, making it ideal for high-production environments. For greater convenience and productivity, PSA products have a light adhesive backing that attaches to a disc pad as easily as a sticker. It removes just as cleanly, leaving an uncontaminated surface for the next sheet. The 3M Microfinishing PSA Film Roll 268L film products are constructed with aluminum oxide, which is a popular choice among industrial professionals because of its fast cut-rate and long life. Due to its fast cut rate, hardness, and strength, it is widely used in sanding and finishing applications. Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys.
