3M™ Finesse-it™ PSA Film Disc 466LA, A5 3MIL, 5 in x NH, Die 500X

Designed for Finishing and Repair
3M™ Trizact™ Finesse-it™ Film Disc 466LA features tiny, sharp pyramids that wear gradually during sanding, continually exposing fresh mineral to give you a consistent cut and a predictable, fine finish.

We chose silicon carbide mineral for this abrasive because, while it breaks down faster than aluminum oxide, it tends to produce a brighter finish. It's commonly used for defect removal on clear coats, paint and plastics because it can effectively refine these surfaces without gouging or damaging the workpiece.

3M™ Science, Applied to Trizact™ Abrasives
3M™ Trizact™ abrasives use 3M microreplication technology, encapsulating mineral inside tiny pyramids. These pyramids are evenly distributed over the backing. While conventionally coated abrasives often have erratically spaced mineral, Trizact™ abrasives focus on uniformity. As pyramids wear, fresh, sharp mineral is exposed to produce a consistent cut and a predictable, fine finish. Altogether, this means fewer scraps and discards as a consequence of inconsistent results. Ongoing sharp cutting action minimizes the need to incorporate other abrasives in the sequence, thereby reducing processing steps and enhancing productivity.

3M™ Trizact™ Finesse-it™ Film Disc 466LA is available in three grades: A3, A5 and A7. The discs are color-coded by grade to reduce the risk for error when there are multiple grades in a sequence. Each disc is designed for quick access and attachment to rotary tools or orbital sanders. Altogether, this disc is a good partner in repairing and finishing workpieces that require a balance between softness and strength — effectively tackling imperfections while maintaining workpiece integrity.
