Rolo de discos de lixa 3M Trizact 466LA Disco em pirâmide Lixa de precisão A3/A5/A7

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 sanding discs have a triangular structure that contributes to a more even surface. This helps reduce the amount of sanding needed to achieve the desired result.

  • Well suited for use on mini random orbital sanders to produce a polish-ready finish
  • Silicon carbide mineral in three very fine micron grades

Fine Sanding and Finish of Automotive Coatings

Available in three grades — A3, A5, and A7 — 3M Trizact Sanding Discs 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.

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 Sanding Discs 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.

3M Trizact Abrasive Discs efficiently remove scratches, swirls and other imperfections from a variety of surfaces. They are also ideal for finishing applications as they leave an even and consistent finish. The micro-replicated structure of the disc surface ensures an even distribution of abrasive particles, thereby reducing the risk of surface damage and ensuring a high standard of surface finish.

3M™ Science. Precision Finishing by Design
3M trizact sanding discs 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.

Restore Polish, Repair Automotive Imperfections
The discs on 3M Trizact Sanding Discs Finesse-it™ Film Disc Roll 468LA are packaged in roll form, which makes dispensing the discs quick, easy and convenient. Simply unwind the roll to reveal new discs. Moreover, the roll protects the discs’ PSA backings and abrasive face from dirt and debris until they’re ready for use. The PSA backing on these discs also helps speed your timeline, as no special tools or accessories are required for disc-to-tool attachment. 3M™ Trizact™ Finesse-it™ Film Disc Roll 468LA is engineered by incorporating silicon carbide mineral into a matrix of repeating microstructures; the film backing minimizes the chance for surface abnormalities. The pressure sensitive adhesive on the back of the film adheres immediately to the tool back up pad. The micro-structured silicon carbide mineral cuts sharply enough to quickly remove imperfections, but not so much so that you risk gouging or marring the surface.

3M™ Trizact™ Finesse-it™ Film Disc Roll 468LA
Conventional abrasives are constructed from randomly spaced and irregular-shaped minerals

Combining the Power of 3M™ Trizact™ and 3M™ Finesse-it™ Abrasives
Derived from proprietary 3M Microreplication technology, 3M Trizact Sanding Discs Abrasives consist of precisely-shaped three-dimensional structures distributed uniformly over the substrate. Unlike conventional abrasives, which are constructed from randomly spaced and irregular-shaped minerals, the uniform configuration of Trizact abrasives helps deliver consistent performance. 3M™ Finesse-it™ products are specially engineered abrasives, compounds, polishes, and buffing pads to be used on OEM and baked refinish paints to remove defects, sand scratches, or swirl marks on a variety of painted surfaces. Finesse-it™ products are an integral part of 3M’s recommended buffing system for repairing surface defects to clear coats, lacquered wood, solid surfaces, gelcoat, powder coat, industrial paint, and acrylic. When Trizact™ and Finesse-it™ are combined — you’re left with an abrasive that strikes the perfect balance for your automotive repair needs.

3M Trizact Sanding Discs Finesse-it Film Sand Roll 466LA uses 3M microreplication technology to form micron-sized silicon carbide particles into tiny ground mineral sand pyramids, which are then coated on a non-compressible polyester backing.

As the pyramids wear, new sharp sand is exposed for even cutting and the expected good surface finish. 3M Trizact Sanding Discs Finesse it film abrasive roll can provide three grain sizes of A3, A5 and A7 for various topcoats, and adapt to most surface effects and process requirements. Each roll consists of 500 individual film-based discs. Quickly access and attach it to a rotary tool or eccentric sander. Unlike traditional abrasives, 3M Trizact Sanding Discs Finesse it Film Roll 466LA is sharper and maintains a consistent cutting force for a desired finish and more uniform quality. 3M Trizact Sanding Discs Abrasive can last several times longer than traditional abrasive discs, and can create precise surface effect control. For example, operators can reduce operating steps, process steps are fewer, and abrasive consumption is more economical. Trizact™ abrasives have a three-dimensional structure evenly distributed across the entire surface, ensuring consistent performance and eliminating disc-to-disc variation.
