The highest quality medical-grade aluminum oxide
90 Micron Tan Aluminum Oxide offers the ultimate in performance and results. Alpha alumina particles are precisely sized and desiccated for even flow and efficient cutting. Other abrasives can clog equipment or cause intermittent flow, due to the presence of oils, contaminants and even slight moisture content. Ideal for bonding and cavity preparation, or for general use on metal, porcelain, acrylic, and non-metal surfaces. For MicroEtcher, PrepStart, PrepStart H2O, and similar air-abrasion units. 1 lb bottle.
