3M™ Cloth Sheet 481W is an abrasive sanding cloth constructed on a heavy, screen backing that features closed coat construction for aggressive sanding action. The silicon carbide abrasive and flexible backing make this cloth an ideal product for dry applications such as metal surface sanding and stock removal.

Screen Sanding Cloth
Our 3M™ Cloth Sheet 481W is best suited for metal sanding and finishing thanks to its durability and fast cutting abrasive material. Its heavy, screen cloth backing provides smooth operation and durability and can conform to the shape of contoured parts for consistent finishing. The abrasive side features closed coat construction for aggressive sanding and a distinct brown color helps to easily differentiate it from other grits and grains.

XD belts are made of a tough but flexible nylon mesh that fits any contoured surface. We designed XD material with a woven low-stretch fabric (scrim) embedded in the nylon structure to provide additional strength and durability. Moreover, we constructed the XD material with a thicker coating of resin for additional heft. The scrim and thick resin coating extend the life of the belt and allow for extended use on ferrous materials or steel. Use this belt when high contact pressure and stock removal are required, and when loading is not a concern.

Silicon Carbide Abrasive
This product primarily uses silicon carbide, which is a popular choice among industrial professionals because of its fast cut-rate and smooth finish. This synthetic mineral is very hard and 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 cleaning and finishing on wood (PDF, 21 Mb) and metal.

3M™ Cloth Sheet 481W is best suited for metal sanding and finishing thanks to its durability and fast cutting abrasive material.

Waterproof and Heat Resistant
3M™ Cloth Sheet 481W also uses a resin bonding which is specially designed to resist thermal and chemical deterioration, which can occur during sanding. This bond is very tough and excellent for precision work on hard and soft surfaces. This also allows for faster sanding and a higher cut rate. The waterproof enables the user to rinse areas of the workpiece and the cloth during use to prevent dust and debris from clogging the points of the abrasive, while producing a faster cut at the same time.
