3M Natural Blend White Pad 3500, constructed of a blend of natural (hog's hair) and synthetic fibers, delivers a high gloss and minimizes swirl marks on a wide range of finishes. First choice for fine polishing with corded electric burnishers, the natural blend white burnish pad can be used with all electric and propane ultra-high speed (1500 rpm or greater) floor machines. Resins are dispersed uniformly throughout the pad for solid performance through the life of the pad. It has an open-textured non-woven construction that resists loading and clogging, providing a washable, reusable pad with a long life. The fiber mat is conformable for increased pad-to-floor contact. Pad is reversible. Application: Burnishing; Diameter: 27 ; Height: 1 ; Color(s): White.
