Lapping and Polishing Slurries


Glycol-based diamond suspension

SPG suspensions are fully water-soluble but do not dry when exposed to air. This makes SPG 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. SPG suspensions are ideal for use with metal lapping/polishing plates (steel, copper, tin, composites). Verify compatibility if used with polishing pads.
