Anything extra you need to know
The 3M? Microfinishing Film Belt 372L is manufactured with a closed coat abrasive surface to increase efficiency and produce a finer finish
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
This film comes in a range of micron grades for complete multi-step sanding and finishing
The 3M? Microfinishing Film Belt 372L features precision, micron-graded aluminum oxide, which is a popular choice among industrial professionals because of its fast cut-rate and fine finish
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 for sanding and finishing applications
The 3M? Microfinishing Film Belt 372L uses a resin bond which is designed to resist thermal and chemical deterioration, which can occur during sanding
This bond is very tough and is an excellent option for precision work on hard and soft surfaces
This also allows for faster sanding and a higher cut rate
The closed-coat construction of the belt means mineral grains cover 100% of the backing, so the abrasive scratches all of the surface that it comes in contact with
It's commonly used on surfaces where loading is less of a problem, making it a good match for hard metals.
What makes this product special
Micron-graded aluminum oxide abrasive cuts fast and provides a consistent, fine finish
Durable polyester film backing provides flexibility for consistent finishing
Resin bonding resists deterioration from heat, extending the life of the abrasive belt
Closed coat construction provides good grain density and helps deliver a finer finish
