Glycol-based diamond suspension

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. OWS diamond suspensions are available as custom formulations in a wide range of viscosities, diamond types, sizes and concentrations.


  • Highly tailor-made: select any diamond type, grit size and concentration.
  • User-friendly thanks to stabilized formulation.
  • Environmentally friendly and easy to clean.
  • Scratch-free polishing also in submicron range.
  • Guaranteed agglomerate-free.
