Product Introduction
The 3M™ Microfinishing Film Sheet 373L quickly cuts, shapes, and polishes, delivering uniform, close-tolerance finishes on various materials. It features precision, micron-graded aluminum oxide, resin-bonded to a high-strength, resilient 5 mil polyester film backing for durability and flexibility on contoured surfaces. The film backing has a friction coating made with quartz mineral. The high-strength film backing maintains its integrity when run wet, unlike paper or cloth, and flexing helps achieve a consistent finish over contours.
