Fine Sanding and Finish of Automotive Coatings
Available in three grades — A3, A5, and A7 — 3M Trizact Finesse-it Film Disc Roll 466LA is the clearcoat spot repair disc used by automotive manufacturers worldwide. In convenient roll form, these discs are designed for quick access and attachment to rotary tools or orbital sanders.
While it breaks down faster than aluminum oxide, silicon carbide produces a brighter finish. It’s commonly used for defect repair on clear coats, paint and plastics, because it can effectively refine these surfaces without significantly gouging or damaging the workpiece.
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. While conventionally coated abrasives often have erratically spaced mineral, 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. Altogether, 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.
