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
