3M™ Sanding Screen Disc 483W, 150, Configurable

The unique characteristics of 3M™ Sanding Screen Disc 483W are its open mesh backing and its sharp, fast-cutting abrasive mineral.

Commonly called "drywall paper," 3M™ Sanding Screen Disc 483W offers extreme resistance to loading on soft woods, drywall and metal by utilizing an open-mesh cloth backing that keeps loading to a minimum and resists the friction and heat of continuous sanding. It is ideal for plaster, drywall and other substrates that would load conventional abrasives with the copious amount of fine, flourlike dust they generate.

A waterproof resin bond allows this disc to be run in wet applications. The disc come in 6 grades from 60 to 180.

A hard and brittle mineral, silicon carbide fractures 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 it wears faster than aluminum oxide, it produces a superior finish.

3M™ Sanding Screen Disc 483W is frequently used in white metal repair operations. Car bodies that have been welded together typically have oily surfaces, so the open mesh backing on this abrasive is useful.

Stamping operations frequently leave imperfections on car panels. 3M screen cloth products are used to sand lightly on the car panels, causing high spots to shine a little brighter. The screen cloth works well because the oily surface does not load.
