Product Introduction
3M™ Microfinishing Film Sheet 472L is engineered to deliver precise, consistent finishes on flat, cylindrical, and contoured parts. Its micron-graded silicon carbide mineral and durable 5-mil polyester backing provide sharp cutting action, excellent durability, and uniform surface refinement across metals, plastics, wood, and other substrates. The anti-slip backsize ensures stability during use, and the open-coat design reduces loading while maintaining long-lasting performance.
