Micron-graded Mineral with Advantages

Available in a broad range of fine micron-graded aluminum oxide, 3M™ Microfinishing Film Sheet 372L features a flexible, film backing with a high-friction coating for better grip.

A polyester film backing is typically stronger than paper backings and more conformable to part profiles. It is waterproof so can be used in wet applications.

A hard resin bond is durable and consistent and will produce consistent finishes and stock removal.

Recommended Applications

Miscellaneous abrasive applications (leather). In a sheet form, the film may be cut. This flexibility enables operators to reap the benefits of a microfinishing film and still tackle tough areas that might be inaccessible to other tools and machines.
