3M™ Trizact™ Finesse-it™ Film Disc Roll 466LA uses proprietary 3M microreplication technology, micron-graded silicon carbide particles are formed into tiny pyramids of abrasive mineral on a non-compressible 3-mil polyester film backing.

  • 3M™ Trizact™ abrasives start sharp and stay sharp, resulting in more predictable finishes and improved, consistent results
  • Ideal for the 3M two-step paint defect repair process for automotive finishes
  • Well suited for use on mini random orbital sanders to produce a polish-ready finish
  • Silicon carbide mineral in three very fine micron grades

  1. What is the 3M™ Trizact™ Finesse-it™ Film Disc Roll 466LA?

    The 3M™ Trizact™ Finesse-it™ Film Disc Roll 466LA is a reliable and durable abrasive disc made for polishing and finishing computer screens, plastic surfaces, painted surfaces among others.

  2. What dimensions does this film disc roll come in?

    This film disc roll measures an A3 size (1-1/4 inches x NH). Each disc has an evenly coated cutting surface that also ensures uniform wear all through the life of the product.

  3. Can you tell me more about how many discs are contained per roll or case?

    Yes! There are approximately 500 discs per roll of Die

  4. 125C, packed four rolls to a box. Meaning one purchase gives you up to 2,000 individual film discs for your application needs!

    . How long can I expect these abrasive sanding pads to last?

  5. . At specific ambient conditions and usage patterns, each pad lasts longer producing efficient results consistently with no dullness thus providing value for money.

    . Is it possible to use other attached Velcro hook attachments on the backing plate when using these films disks?

  6. . Yes! For better performance of our disk system attachment we strongly recommend using our compatible Hookit back-up pads which guarantee secure attachment allowing easy change-out resulting in optimized production efficiency as well as cost-effectivenes

Fine Sanding and Finish of Automotive Coatings

3M™ Trizact™ Finesse-it™ Film Disc Roll 466LA is a clearcoat spot repair disc used by automotive manufacturers worldwide. It is available in three grades: A3, A5, and A7. These discs are designed for quick access and attachment to rotary tools or orbital sanders, and are available in a convenient roll form.

Silicon carbide, which is used in the production of these discs, produces a brighter finish and is commonly used for defect repair on clear coats, paint, and plastics. It can effectively refine these surfaces without significantly gouging or damaging the workpiece. Although it breaks down faster than aluminum oxide, it is still a preferred choice for many automotive manufacturers.

Recommended Applications

Machine Sanding

  • Level/remove the defect using the 3M™ Elite Series Mini Orbital Sander 28737 or the 3M™ Mini Random Orbital Nib Sander 20244 and a 3M™ Trizact™ Finesse-it™ 466LA disc
  • Spray the disc with water to prevent the abrasive from loading during sanding
  • Sand the defect for 1 to 3 seconds, depending on its size
  • Wipe the area clean with a Scotch-Brite™ High Performance Cloth

Hand Sanding

  • Level/remove the defect using a 3M™ Finesse-it™ Hand Pad and a 466LA disc
  • Spray the 466LA disc with water to prevent the abrasive from loading during sanding
  • Sand the defect for 3 to 5 seconds, depending on its size
  • Wipe the area clean with a Scotch-Brite™ High Performance Cloth

Automotive Finishes

Remove small defects with a 466LA A5 disc. Sand in a circular motion, holding the pad flat to ensure a fine uniform finish.

3M™ Science. Precision Finishing by Design.

3M™ Trizact™ structured abrasives are precisely shaped engineered composites evenly distributed and bonded to an abrasive backing. These extremely uniform abrasive structures can take the form of almost any three-dimensional geometric shape, including pyramids, hemispheres, and cubes, designed to enhance grinding performance. Trizact™ abrasives are identical in height and orientation, wearing just as uniformly. As they do so, fresh, sharp mineral is exposed to produce a consistent cut and a predictable, fine finish. This means fewer rejects and less rework due to out of spec results. Ongoing sharp cutting action minimizes the need to incorporate other abrasives in the sequence, thereby reducing processing steps and enhancing productivity.

In addition to high-performance abrasives, 3M microreplication technology is also used in the manufacture of a variety of 3M products such as overhead projector lenses, reflective traffic signs, and solar optical films. It's science, making your world smoother and brighter.
