3M 405U Silicon Carbide Abrasive Sheet

One of our best paper-backed sheets, our 3M™ paper sheet 405U is a silicon carbide sheet constructed on an A-weight, light paper backing. It features a load-resistant coating and open-coat construction. Few shops can do without abrasives in handy sheet form and our 3M™ paper sheet 405U is built to be indispensable. A flexible A-weight paper backing provides excellent conformability and silicon carbide abrasive mineral delivers exceptional finishes. Our silicon carbide abrasive sheets create a smoother finish than aluminum oxide products on most substrates. While it breaks down faster than aluminum oxide, it produces a superior finish. A resin bond construction provides superior grain retention while the open-coat construction, along with the load-resistant coating, combine to provide excellent anti-loading characteristics. These versatile sanding sheets contain the ideal abrasive grain type and grades for multi-step finishing processes.
