The Benefits of Silicon Carbide Abrasive Sheets

Silicon carbide abrasive sheets are a superior choice for achieving a smooth finish on painted metal and wood substrates. Compared to aluminum oxide or garnet abrasive products, silicon carbide creates a smoother finish.

The resin bond construction of these sheets provides superior grain retention, while the open coat construction and load resistant coating combine to provide excellent antiloading characteristics. The light A-weight backing of the sheets provides conformability over contours and into crevasses and corners.

These versatile sanding sheets can be easily cut to fit a hand pad block, inline sanders, or finishing or power sanders. They are ideal for general sanding, finishing, blending, surface leveling, and prep prior to staining or painting.

Containing the ideal abrasive grain type and grades for multi-step finishing processes, silicon carbide abrasive sheets are a must-have for any finishing project.

The Benefits of Silicon Carbide Mineral

Silicon carbide is a synthetic mineral that is commonly used for final finishing in white wood sanding. While it breaks down faster than aluminum oxide, it produces a superior finish.

Its sharpness and hardness make it an excellent choice for achieving a smooth finish on a variety of surfaces.

When it comes to achieving a high-quality finish, silicon carbide is the way to go.
