Achieve Close-Tolerance Finishes3M™ 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, fiberglass, metals and in paint preparation. 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.The Convenience of Pressure Sensitive AdhesiveFor 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.Fast Cut, Long Life3M™ 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. This mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges. 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.
