RTZ WASHCOAT : A zircon based refractory coating widely used throughout the mining, foundry and engineering industries, in refractory situations where extended life and added protection is desired.
Crucibles : Crucible erosion can be greatly reduced by evenly coating the inside and outside of each crucible with RTZ Washcoat prior to use. RTZ Washcoat assists in preventing Black Spot i.e. Carbon Pick up from Clay Graphite crucibles thus preventing staining on gold bars.
Furnaces: RTZ Washcoat protects and increases the life of insulation materials in furnaces. Brickwork can also be protected from chemical and slag attack by brushing on RTZ.
Moulds: Because of its non-stick properties, RTZ Washcoat works exceptionally well as a releasing agent on gold moulds. Gold bars slip out easily, requiring little cleaning.
