Description

RTZ Washcoat is paintable and sprayable super-high temperature ceramic refractory for lining, repairing, and protecting the inside of your forge. Zirconia based with a melting point of 2715°C, the same material used to clad nuclear reactors. Widely used throughout the mining, foundry and engineering industries, in extremely high temperature 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 R.T.Z prior to use.  R.T.Z. assists in preventing Black Spot i.e.: Carbon Pick up from Clay Graphite crucibles thus preventing staining on gold bars. Furnaces:  R.T.Z Wash Coat protects and increases the life of insulation materials in furnaces.  Brickwork can also be protected from chemical and slag attack by brushing on R.T.Z. Moulds:  Because of its non-stick properties, R.T.Z works exceptionally well as a releasing agent on gold moulds.  Gold bars slip out easily, requiring little cleaning. After adding kaowool to your forge, coat with rigidiser, then apply a thin coating of RTZ Washcoat and wait a few days for curing before your first firing.
