Diamond suspension for lapping and polishing of sapphire, ruby, ceramics, metals and other superhard materials:
SPG are water-soluble suspensions designed for lapping and polishing of ceramics and metals. The product is widely used for finishing of sapphire, ruby, silicon carbide, tungsten carbide and other super-hard materials. SPG 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 SPG allow for high lapping pressures and thus high removal rates.
