Silicon Carbide Abrasive

Standard Abrasives™ Cleaning Pro Disc is lined with silicon carbide, which is a popular choice among industrial professionals because of its fast cut-rate and smooth finish. Silicon carbide is a very sharp synthetic mineral commonly used in low-pressure applications like paint prep. While the mineral breaks down faster than aluminum oxide, it produces a finer finish. This makes the Standard Abrasives™ Cleaning Pro Disc best suited for sanding and finishing applications on fiberglass, composites or soft metals.

Open Coat Construction

Abrasives cut better and last longer when dust isn’t clogging the cutting surface. Open coat construction means the abrasive grains are placed with space between them to help evacuate sanding debris and avoid clogging of the grains’ cutting edges. Additionally, the open coat feature provides a more aggressive cut than a comparable closed coat abrasive of the same grade. This all adds up to increased productivity and reduced material consumption.
