3M 435U Silicon Carbide Abrasive Sheet

Our 3M™ paper sheet 435U is an abrasive sheet coated with a silicon carbide abrasive grain constructed on a C-weight paper backing. This sheet is ideal for sanding wood by hand. Cut or tear standard 9 x 11 in sheets to the dimensions you need. Best among our abrasive sheets for sanding woods of all types, the 3M™ paper sheet 435U features a silicon carbide mineral in three grades. Silicon carbide is a synthetic mineral that is very sharp and commonly used for final finishing in white wood sanding. Silicon carbide abrasive sheets create a smoother finish than aluminum oxide abrasive products on wood as well as composite and advanced material substrates. Its 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. Abrasive mineral stays clean and cutting, extending abrasive life.
