    Extra Product Information

  • The 3M Microfinishing Film Disc 468L is made using micron-graded silicon carbide, which is a popular choice among industry professionals because of its fast cut and smooth finish
  • Silicon carbide is a very sharp mineral commonly used for low-pressure applications, such as sanding and finishing during paint prep
  • While it breaks down faster than aluminum oxide, this mineral produces a brighter finish
  • The disc's 3 mil (0.08) film backing flexes to help achieve a consistent finish over contours and offersgood tear-resistance, making it ideal for high-production environments
  • Abrasives cut better and last longer when dust isn?t clogging the cutting surface of the abrasives
  • Open coat construction means the abrasive grains are placed with space between them to help evacuate sawdust and other sanding debris and avoid clogging the cutting edge of the grains
  • This also allows the abrasive to continue cutting even when sanding softwoods, paints, and other materials that would, otherwise, clog the disc and hinder sanding ability
  • Additionally, the open coat feature provides a more aggressive cut than a comparable closed coat abrasive of the same grade.

    • Product Information

  • Ideal for sanding metals, plastics, wood, paint, e-coat, and composites
  • Open coat construction provides aggressive cut and reduced loading
  • Silicon carbide mineral produces consistent finishes
  • Strong 3 mil polyester film backing
  • Use wet or dry
