Highlights
High friction coating on film backing (backsize) to prevent slipping
Ideal for metal, plastic, paint spot repair and automotive powertrain components
Micron-graded aluminum oxide abrasive mineral provides precise, uniform, close-tolerance finishes
Resin bond Sheet may be cut and shaped for hand pads or back up pads
3M Microfinishing Film Sheet 372L is fast cutting and delivers a precise, uniform, close-tolerance finish. A high friction coating on 5 mil polyester film backing helps to prevent abrasive from slipping. Use on metal, plastic, paint spot repair, automotive power train components and more.
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.
