3M 7010329020 | Scotch-Brite 7-1/2" OAD x 4-1/2" Hole Diameter Extra Coarse Silicon Carbide Marine Cleaning Disc

The Scotch-Brite Marine cleaning disc was designed for a unique purpose and its name relays its intent: to help operators clean up ship propellers when there's more than just scum to remove.

The Scotch-Brite Marine cleaning disc removes marine growth, tubeworms, barnacles, calcium and basal plate build-up from ship propellers. This nonwoven disc offers a fast, clean method to replace costly, strong chemicals and time-consuming scraping by hand. As operators know well, propellers are an integral part of boating operations; keeping these parts clean is important for optimal boat performance. Propellers contribute to both acceleration and fuel efficiency. When weighted down by growth and debris, they cannot run as smoothly and require more fuel to sustain the same speed. Cleaning propellers helps reduce overall friction and resistance, so they can move more smoothly through the water.

The Scotch-Brite Marine cleaning disc is engineered by combining silicon carbide mineral and nonwoven nylon fibers with resin. The mineral is extra coarse (XCS), meaning it cuts especially sharp compared to finer grades. This mineral is tough enough to remove the growth that resides on propellers. Still, the nonwoven nylon fibers are responsive enough to not gouge the propeller or severely alter its geometry and remove the underlying gelcoat. The disc is available in two densities, so operators can choose the right density for their propeller.

The disc has hook and loop attachment for easy changeout of discs. It speeds the process by eliminating the need to work with fickle attachment systems. The hook-and-loop backing is designed to be used with hook-and-loop holder pads (sold separately). The hook-and-loop attachment acts like a cushion, providing some extra shock-absorption and buoyancy. When run under normal use, the likelihood of gouging or denting the workpiece is reduced.

Nonwoven technology makes Scotch-Brite industrial abrasives unique. A combination of fiber strands, resin, and abrasive mineral forms a thick, open web. The spring-like nature of the fibers responds to contours and effectively removes unwanted burrs, soils, and contaminants while maintaining the geometry of the workpiece, which in turn reduces rework and boosts productivity.

Gaps in the web allow swarf to escape, so debris does not clog the mineral. Fibers in the web continually break down with use to reveal fresh mineral for exceptional consistency, superior cut performance, and extremely long service life. From aesthetic finishing to weld blending, deburring, and more, Scotch-Brite abrasives work fast and deliver consistent results, part after part.
