Silicon Carbide and PSA Film Backing
We engineer 3Mâ„¢ Microfinishing PSA Film Sheet 468L using micron-graded silicon carbide, which is a popular choice among industrial professionals because of its fast cut and smooth finish. Silicon carbide is a synthetic mineral that is very sharp and 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 brighter finish.
The thin 3 mil film backing on 3Mâ„¢ Microfinishing PSA Film Sheet 468L flexes to help achieve a consistent finish over contours and is a smart choice for close tolerance applications. The backing also offers greater tear-resistance than comparable paper products, making it ideal for high-production environments.
Designed for use with a variety of tools including orbital and random orbital platen sanders, this abrasive sheet comes in a range of micron grades for complete multi-step sanding and finishing, and can be cut to size depending on the tool. The pressure sensitive adhesive (PSA) provides flat, easy attachment, holds the sheet securely in place during use, and removes cleanly from the backup pad (sold separately).
Provides Maximal Productivity
Abrasives cut better and last longer when dust isn’t clogging the cutting surface of the abrasives. This film sheet’s abrasive grains are placed with space between them to help evacuate sawdust and other sanding debris and avoid clogging the cutting edge of the grains. This also allows the abrasive to continue cutting even when sanding softwoods, paints, and other materials that would, otherwise, clog the disc and hinder sanding ability. All of this adds up to increased productivity and reduced material consumption.
3M Abrasives for Finer Finishes
Microfinishing – an important application for many operators – corrects the geometry of parts and creates fine finishes. Microfinishing can remove damaged or amorphous layers to improve the surface finish and roundness of the part. Available in variety of grades, operators should consider target tolerances when selecting the right microfinishing film.
To improve the geometry of parts and achieve desired finishes, our 3Mâ„¢ Microfinishing PSA Film Sheet 468L is an exceptional choice.
