3M™ Microfinishing Film Unbacksized Sheet 366L, 100 Mic 3MIL, Type D, Config

Designed with High-Production Environments in Mind
Made with a load-resistant coating, 3M™ Microfinishing Film Unbacksized Sheet 366L was designed to combat the dust and debris that substrates like wood tend to produce. The coating helps prevent mineral from dulling prematurely, so it can keep cutting fast and sharp. The abrasive is resin-bonded and supports flexibility without sacrificing durability and reliable performance. The polyester film flexes to help achieve a consistent finish over contours and offers greater tear-resistance than comparable paper products. As it can withstand wear and retain its shape, it's a good match for high-production environments.

Aluminum Oxide for Fast Cut and Fine Finish
3M™ Microfinishing Film Unbacksized Sheet 366L features precision with 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, whereas traditional natural abrasives dull more quickly. 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.

Equally Matched
From transportation and heavy equipment to general industrial, paint preparation, woodworking and composite materials, 3M™ Microfinishing Film Unbacksized Sheet 366L tackles imperfections across industries. Its load-resistant coating helps enhance its effectiveness and longevity. The sheet form sets it apart from other 366L products. The material can be cut and shaped to match the dimensions a project requires. It's also color coded by grade to help reduce the risk for error when multiple grades are in a sequence. Combine technical attributes – like mineral and backing color coding – and you've got an abrasive equally matched in strength and usability.

• Precision, micron-graded aluminum oxide abrasive offers a fast cut, long life, and uniform finish on many substrates
• Durable polyester film backing provides flexibility for consistent finishing on contoured surfaces
• Load-resistant coating prevents dust and debris from clogging the disc
• Sheet form means abrasive may be cut and shaped per project requirements
