POLISHING COMPOSITIONS OTHER THAN FRENCH POLISH; SKI WAXES
Definition statement

This place covers:

  • Polishing compositions containing abrasives or grinding agents as well as polishing compositions based on aqueous dispersions, such as chemical mechanical polishing slurries for polishing semi conductors.
  • Polishing compositions based on wax -this includes compositions based on mixtures of wax and natural or synthetic resins- and polishing compositions based on non-waxy substances, e. g. natural or synthetic resins.
  • Ski waxes
