Fine polishing suspensions for perfect metallographic sample preparation

QPREP fine polishing suspensions are the polishing products of choice for the most demanding polishing requirements. In this process, a chemical-mechanical polishing is performed using colloidal silicon dioxide or aluminum oxide. A colloidal suspension is a heterogeneous mixture, in which fine particles are evenly distributed in a liquid, and do not settle. Fine polishing suspensions with colloidal silicon dioxide utilize this stability for effective and gentle polishing, which improves surface quality and consistently delivers high-quality results.
