Water soluble suspension designed for lapping and polishing of ceramic and metals. The product is widely used for finishing of sapphire, ruby, silicon carbide, tungsten carbide and other super hard materials. OWS suspension is fully water-soluble but does not dry up when exposed to air. This makes it a perfect product to replace oil-based polishing fluids. The excellent lubrication properties of OWS allow for high lapping pressures and thus high removal rates.
