Ceramic-Coating LE is a special coating on the basis of CaO stabilized zirconium oxide. Contrary to the frequently used zircon (zirconium silicate) zirconium oxide indictaes a substantially better stability and temperature stress. Ceramic-Coating LE shows a high hardness and is extremly abrasive resistant. By its small porosity the permeability of gas is extremly small. Ceramic-Coating LE is preferebly used as a protection and interface for graphite and ceramic crucibles. Within the metallurcigal area crucibles, troughs, dies and thermocouples are coated with this product in order to obtain very pure melts and clean casting surfaces. The substrates which can be coated should indicate thermal coefficients of expansion of <8.5·10-6/K. For substrates with clearly higher thermal coefficients of expansion the product Ceramic-Coating HE is available.
Ceramic-Coating LE can be used both at air as well as under vacuum and inert gas to 1500°C, briefly this may be exceeded.
Resuspend Ceramic-Coating LE
prior to use. Dilute with distilled water
Containers should be kept closed and product protected against frost. A storage temperature of >5°C (>41°F) is recommended. Ceramic-Coating LE is available in 1kg-containers.
Ceramic-Coating LE contains water, is solvent-free and according to data available to us a non-hazardous preparation. This product is alkaline and therefore labelled irritant. The use of eye and hand protection is recommended. An EC material safety data sheet is available.
