Description

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. The flexible A-weight paper backing provides excellent conformability and silicon carbide abrasive mineral delivers exceptional finishes. Silicon carbide abrasive sheets create a smoother finish than aluminum oxide products on most substrates, and while it breaks down faster than aluminum oxide, it produces a superior finish.
