PRODUCT FAQ

What is the purpose of 3M™ Microfinishing Film Roll 372L?

The 3M™ Microfinishing Film Roll 372L is designed to provide a consistent and precise finish on surfaces such as metals, plastics, and painted surfaces. It's commonly used in automotive repair and maintenance shops, as well as for industrial applications.
Can you tell me more about the specifications of this product?

Certainly! This particular roll has a micrometer rating of 80 microns (or .003 inches), measures 4 inches wide by 150 feet long, features a keyed core design for easy installation, and comes in an attractive purple color. Additionally, each case contains four separate rolls.
How do I know if this product is right for my specific needs?

We recommend reviewing your project requirements carefully before selecting any abrasive material. If you're unsure whether or not the 3M™ Microfinishing Film Roll 372L is the right choice for your job, our team can help answer any additional questions you may have to ensure that you select an abrasive material that will meet your roughness/finish requirements while also being cost-effective.

For industrial/occupational use only. Not for consumer sale or use.

3M industrial and occupational products are intended, labeled, and packaged for sale to trained industrial and occupational customers for workplace use. Unless specifically stated otherwise on the applicable product packaging or literature, these products are not intended, labeled, or packaged for sale to or use by consumers (e.g., for home, personal, primary or secondary school, recreational/sporting, or other uses not described in the applicable product packaging or literature), and must be selected and used in compliance with applicable health and safety regulations and standards (e.g., U.S. OSHA, ANSI), as well as all product literature, user instructions, warnings, and other limitations, and the user must take any action required under any recall, field action, or other product use notice. Misuse of 3M industrial and occupational products may result in injury, sickness, death, or property damage. For help with product selection and use, consult your on-site safety professional, industrial hygienist, or other subject matter expert.

Predictable, Consistent, Repeatable Performance

3M™ Microfinishing Film Roll 372L achieves an extremely consistent scratch for microfinishing by using micron-graded mineral, measured at tight size tolerances. The resin bond ensures reliable, consistent performance. The abrasive has a durable film backing that helps achieve tight geometry and finish tolerances. This microfinishing roll comes in a broad range of micron grades to achieve reproducible surface characteristics and geometric values that adhere to specification.

3M designed Type 2 film in a range of colors to reduce the risk of operator error. The color coding is a useful visual cue, as is sorting width by core size and side and end of roll printing and marking. In some applications, numerous grades are run simultaneously to achieve finishes that differ across the surface of a single complex part.

Film Backing Provides Uniformly Flat Vehicle for Finer Finish

Film backings provide a superior, uniformly flat surface to hold abrasive particles. Abrasive grains don't compress or become pressed into the backing. The polyester film backing is highly conformable and tear-resistant, flexing to help achieve a consistent finish over contours. It is stronger than comparable paper products, making it ideal for high-production environments.

For Flawless Geometries

Manufacturers of critical automotive components have little room for error in producing parts to specification. Microfinishing removes variations in the surface, minimizes friction, and manipulates metal behavior in other ways. Engine component surfaces and geometry can be improved by using microfinishing, which is essential for finishes of crankshafts and camshafts that rotate on increasingly thinner films of oil.

Recommended Applications

3M™ Microfinishing Films are used in the production of industrial components such as custom flanges and fittings for the oil and gas industry, as well as superfinishing of automotive parts, like crankshafts, camshafts, and transmission parts.
