Silicon Carbide

• Silicon carbide is a very hard mineral characterized by sharp points that fracture easily, resulting in freshly exposed sharp edges that cut extra fast and produce a smooth, professional-looking finish. Silicon carbide products are commonly used for low-pressure applications such as paint prep and finishing on wood and metal. While the mineral has a shorter life than aluminum oxide, it produces a superior finish.

Wetordry

• 3M Wetordry products are backed with a 3M patented durable waterproof paper backing that supports both wet and dry applications. Lighter weight than cloth and smooth rather than textured, paper backing is preferable for lighter applications such as finishing and paint prep. At the same time, many such applications produce a significant amount of dust, clogging the abrasive points and creating an inferior work environment. These effects can be minimized by sanding with water to rinse dust away from the workpiece and the abrasive surface.
