for the coating of ceramics, fibre ceramics, graphite and metals
good chemical stability
for high temperature applications to 1900°C
contains stabilized zirconium oxide
Zirconia-Coating ZR-A is a special coating based on CaO-stabilized zirconium oxide. Contrary to the frequently used zircon (zirconium silicate) zirconium oxide shows a substantially better stability and temperature stress. Zirconia-Coating ZR-A is preferably used as protection and interface for graphite and ceramic crucibles, refractory bricks and fibre ceramics as well as for coating kiln furniture, supports and trays.
Within the metallurgical field of application Zirconia-Coating ZR-A can be used for coating crucibles, troughs, dies and thermocouples in order to obtain very pure melts and clean casting surfaces.
Due to its small grain size Zirconia-Coating ZR-A can be applied in thin layers (max. 200µm) only. For thicker layers the product Zirconia-Coating ZR-O is available. As an inexpensive version Zirconia-Coating ZR-M is recommended, based on unstabilized zirconium oxide.
Zirconia-Coating ZR-A can be used both at air as well as in the vacuum and inert gas to 1900°C. On graphite an application to approximetaly 1500°C is possible.
Zirconia-Coating ZR-A before use. If necessary, dilute with distilled
Keep containers closed and protect against frost. A storage temperature of >5°C (>41°F) is recommended. Zirconia-Coating ZR-A is available in 1kg-containers..
Zirconia-Coating ZR-A contains water and is free of solvents. According to data available to us Zirconia-Coating ZR-A is a non-hazardous preparation. An EC material safety data sheet is available.
