Water-soluble diamond suspension

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.

SPG highlights

  • Highly tailor-made: select any diamond type, grit size and concentration.
  • User-friendly thanks to stabilized formulation.
  • Environmentally friendly and easy to clean.
  • Good lubrication.
  • Narrow particle size distribution.
  • SPG-100 is anti-corrosive.
