Product Details
  • Durable film backing is tear-resistant and provides a uniform finish
  • Flexible film sheet conforms smoothly to contours and rounded edges
  • Versatile abrasive suits many applications for woodworking and paint prep
  • Premium mineral delivers a faster cut and extended life
  • Load-resistant coating and open coat construction help prevent dust and debris from clogging the abrasive
  • Easy-to-use 3M™ Hookit™ attachment system enables quick product change-outs

We engineered 3M™ Hookit™ Film 375L abrasive to deliver outstanding tear resistance, flexibility and consistent finish on a variety of substrates. The film backing conforms to contours and delivers a super smooth application that produces a highly uniform finish. Premium aluminum oxide grain offers a faster cut and extended product life over standard A/O mineral for greater productivity.

Tear-Resistant Film Achieves Superior Finish
3M™ Hookit™ Film 375L is excellent for a variety of applications. In coarse grades, it is a great choice for demanding applications that require greater durability. For general purpose finishing, the 375L film in medium grades conforms well to the contours and rounded edges of challenging work surfaces to deliver a superior finish. Woodworking applications are further enhanced by a load-resistant coating and open coat construction, which reduce clogging and extend the life of the abrasive. For pre- and post-paint finishing, versatility is key, and our 375L film in fine grades is designed to deliver a superb uniform finish on plastics and clear coat technologies commonly used in the transportation industry.

Achieve Consistent Results on Many Substrates
Film-backed abrasives have excellent tear-resistant properties and provide a very uniform finish and consistent results with each use. This makes them an excellent option when working on paint, e-coats, primers, gel coats, glass, acrylics and solid surface material, wood topcoats and anywhere else you need a quality finish every time.

Faster Cut, Longer Life
We use premium aluminum oxide abrasive mineral in the manufacture of our 3M™ Film 375L. Aluminum oxide 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.

The Convenience of 3M™ Hookit™
The Hookit™ hook-and-loop feature makes sheet attachment, removal, and re-attachment clean and easy, and facilitates use and re-use of the sheet for the full extent of its abrasive life. Hookit™ sheets have the brushed nylon loop backings that grip the J-shaped hooks of 3M™ Hookit™ disc backup pads. It's simple: just set the sheet in place and start sanding. The sheet removes just as cleanly and easily. The Hookit™ system is designed for work spaces and applications where adhesive backed sheets may become contaminated by dust, dirt, or flying debris.
