Saint-Gobain Abrasives, Inc. has introduced Norton Finium abrasive microfinishing film rolls for precision applications. Norton Finium 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 exceptional surface finish uniformity, while positioning Norton Finium film products as the most advanced in the market. 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 very large engine manufacturing operations around the world. Film rolls are made in extremely fine grit sizes, available in 80 – 9 micron/μ or 180 – 1,000 grit of straight and scalloped edge. The micron 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. The Norton Finium line is manufactured under controlled operations to ensure the highest quality, uniformity and consistency. This line of coated abrasive film complements the Norton lines of bonded abrasive (grinding wheels) and superabrasives (diamond and cBN) products also used in the powertrain markets.
