The 3M Microfinishing Film Sheet 373L quickly cuts, shapes and polishes, delivering uniform, close-tolerance finishes on metal parts as well as rubber, plastic, and composites. Premium aluminum oxide mineral is resin-bonded to a 5 mil, high-strength polyester film backing that provides durability and flexibility for consistent finishing on contoured surfaces. Use wet or dry.
Achieve Close-Tolerance Finishes
The 3M Microfinishing Film Sheet 373L features precision, micron-graded aluminum oxide, resin-bonded to a high-strength, resilient polyester film backing to produce a fast cut-rate and precise, uniform finish on metal, solid surface composites, rubber and plastic. The film backing has a friction coating made with quartz mineral.
To complement the effective abrasive action, the polyester film backing flexes to help achieve a consistent finish over contours and offers greater tear-resistance than comparable paper products, making it ideal for high-production environments. The strength of the backing, combined with the uniformity of the mineral, helps produce a consistent finish each time you sand.
Aluminum Oxide Suits Many Surfaces
3M gave 373L products precision, micron-graded aluminum oxide, which is a popular choice among industrial professionals because of its fast cut-rate and long life. This mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges. Due to its fast cut-rate, hardness, and strength, it is widely used in grinding applications in addition to sanding and finishing applications. Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys.
Run It Wet or Dry
Coolant generally extends abrasive life, increases cut rate, prevents loading, and reduces air-borne particles. The high-strength, film backing with anti-slip coating maintains its strength and flexibility when run wet, while paper or cloth can disintegrate.
