3M™ Microfinishing PSA Film Disc by 3M

The 3M™ Microfinishing PSA Film Sheet 268L is a fast-cutting abrasive for precise, uniform, close-tolerance finishes. Aluminum oxide is resin-bonded to a 3 mil (0.08 mm), 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 sanding block. Use wet or dry.The 3M Microfinishing PSA Film Sheet 268L features precision, micron-graded aluminum oxide resin-bonded to a high-strength, resilient polyester film backing to produce a fast cut rate and precise, uniform finish on wood, solid surface composites, plastic, fibreglass, metals, and paint preparation. The film backing offers great flexibility without sacrificing the durability and reliable performance of the sheet. 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.
