Type Z

Type Z is a water-based, relatively soft washcoating of Calcia-Stabilized (4 wt%) Zirconium Oxide that is usable to over 1500 C in NON-AIR atmospheres.   Available in 1 gallon container.

               *Note:  Type Z should NOT be used in air atmospheres: use Z Aerosol in that case.


Key Attributes

  • Provides, in a water-based paint, the properties of ZrO2 – lowest thermal conductivty; good high-temperature stability with molten metals, glasses, slags, and salts; inert barrier for reactions, diffusion bonding, brazing etc.
  • Applies like housepaint (brush, dip, air-spray)
  • Easily applied by air spraying on to hot or cold graphite crucibles and molds
  • Good with highly reactive molten metals
  • Safe, Water-Based

Ideal Uses

  • Graphite crucibles and molds
  • Anti-stick with diffusion bonding
