Technical Specifications

  • Silicon carbide is ideal for general purpose sanding on wood, metal, plastic, dry wall, fiberglass, glass and ceramic
  • Light A-weight paper backing has excellent conformability
  • Great for contour sanding
  • Fast cutting silicon carbide delivers exceptional finishes
  • Load-resistant coating and open coat construction minimize loading for better finish and longer abrasive life

Extra Fine and Indispensable
Few shops can do without abrasives in handy sheet form, and 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.

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.
