Film Disc Roll, suited for Machine Sanding, Hand Sanding, Automotive Finishes
Film Disc Roll uses proprietary microreplication technology, micron-graded silicon carbide particles are formed into tiny pyramids of abrasive mineral on a non-compressible 3-mil polyester film backing.
Fine Sanding and Finish of Automotive Coatings
Available in three grades -- A3, A5, and A7 -- Film Disc Roll 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
Hand Sanding
Automotive Finishes
Remove small defects with a 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, 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.
- Abrasives start sharp and stay sharp, resulting in more predictable finishes and improved, consistent results
- Ideal for the 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
