This coating is a Graphite, alumina silicate top coating in isopropyl alcohol. It is ideal for coating of sand moulds and cores used for casting of grey or nodular cast iron and non-ferrous alloys.


It can be applied:

  • by brushing
  • by dipping
  • by flooding
  • by spraying

When dipping or spraying the coating must be diluted by ethanol or isopropyl alcohol. The coating should be well mixed before use or dilution. It is recommended to check the readiness of the coating using a viscometer or using a Baume hydrometer. The coating can then be hardened in air or by flaming off.
