3M™ 7100041315 Paper Sheet, 11 in L x 9 in W, 400 Grit, Fine Grade, Silicon Carbide Abrasive, Paper Backing

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. The light A-weight backing provides conformability over contours and into crevices and corners. The sheet can also be easily cut to fit a hand pad block, inline sander or finishing or power sanders. Other applications include general sanding, finishing, blending, surface leveling, prep prior to staining/painting and scuff sanding between coatings.
