Saint-Gobain Abrasives Inc. has introduced Norton Finium abrasive microfinishing film rolls for precision applications. Norton Finium products, positioned in the "Best" tier of Norton film products, are designed with a new, patented topside resin system alongside two new backing types and an innovative grit size color coding. This combination is specifically engineered to deliver high material removal and surface finish uniformity.

The new Norton Finium line, designated Q351R and Q351S, features either a rough (R) back or smooth (S) back film, to meet any application requirement and equipment type. These microfinishing film rolls are used in powertrain polishing operations in the automotive, truck, marine, small engine, and large engine manufacturing operations around the world. Film rolls are made in extremely fine grit sizes, available in 80 to 9µm or 180 to 1,000 grit of straight and scalloped edge. Theµm size is so fine that it can be difficult to distinguish visibly one from the other, which is critical in selection process.

"We have added a color code by grit size as visible identity verification to simplify selection to avoid mistakes inside our customers manufacturing plants," says Alexandre Pecora, Product Manager for Film for Saint-Gobain.
