Silicon Carbide and Film Backing
3M™ Microfinishing PSA Film Disc Roll 468L using micron-graded silicon carbide, popular among industrial professionals for its fast cut and smooth finish. The shard-like shape of silicon carbide and its extremely hard character make it desirable for hard materials. It is commonly used for low-pressure applications, such as sanding and finishing during paint prep. While it breaks down faster than aluminum oxide, this mineral produces a finer finish.

The 3 mil film backing on these discs flexes to help achieve a consistent finish over contours and offers greater tear-resistance than comparable products, making it ideal for high-production environments.

Easy PSA Attachment and Applications
Designed for use with a variety of tools including rotary, orbital, and random orbital platen sanders, this abrasive comes in a range of micron grades for complete multi-step sanding and finishing. These discs is used for paint prep, finishing and repair on wood, clear coats, composites and plastics. The pressure sensitive adhesive (PSA) provides flat, easy attachment, holds discs securely in place during use, and removes cleanly from the backup pad (sold separately).

The Ease of a Disc Roll, Simple Adhesive Attachment
Convenient disc roll form is economical and easy to use. Multiple discs in roll form with a liner. Disc rolls can be kept as a single unit. Tear off one at a time for speed and efficiency. These ready-to-use discs feature a pressure sensitive adhesive coating on the back – simply press the disc onto the backup pad and you’re ready to go. They remove just as cleanly, leaving an uncontaminated surface for the next disc.
