3M Microfinishing Film 268L: 8.5 in. x 11 in. Sheet

3M microfinishing film 268L supports precision sanding and finishing where close tolerances and uniform surface quality matter. This 8.5 in x 11 in. film sheet uses micron-graded aluminum oxide bonded to a durable polyester film backing, delivering controlled cutting action across a wide range of substrates. The flexible film construction performs well in high-production environments requiring consistent results.

Micron-Graded Aluminum Oxide for Precision Finishing

3M microfinishing film 268L features precision aluminum oxide abrasive designed for fast cutting action and long service life. The abrasive grain fractures during use to maintain sharp cutting points, supporting uniform finishes on wood, plastics, composites, fiberglass, metals and painted surfaces. This controlled abrasive performance suits both woodworking and metalworking applications.

Durable Polyester Film Backing for Contours and Edges

A high-strength polyester film backing provides flexibility without sacrificing durability. The film backing conforms to contoured surfaces while offering greater tear resistance compared to paper-backed abrasives. This construction helps maintain consistent finishes across edges and complex shapes during sanding and finishing operations.

Pressure-Sensitive Adhesive for Easy Attachment

The PSA backing allows fast attachment to sanding blocks or disc pads without additional adhesives. Each sheet removes cleanly, leaving a residue-free surface ready for the next abrasive. This attachment method supports efficient changeovers in production-focused workflows.

Wet or Dry Operation for Process Flexibility

3M microfinishing film 268L performs well in wet or dry sanding applications. Using coolant or water helps reduce loading, control airborne particles and extend abrasive life. The film backing maintains strength and flexibility during wet operation, supporting consistent cutting performance. Contact Waters Industrial today for more information.
