Type ZO Blackbody

Type ZO Blackbody is a high-emissivity version of Type ZO.   This water-based paint of 4% CaO Stabilized ZrO2 is good for coating all substrates that are compatible with pH-Acidic (like lemon juice) conditions.  The paint is usable to 1800 C (3272 F) in all atmospheres.


Key Attributes

  • High Emissivity Coating (“HEC”), estimated >0.9 with proven use to >1700
  • >92% Zirconium Oxide on heating above 600 C
  • Resistant to Many Molten Metals and Alloys
  • Very Low Thermal Conductivity
  • Low Electrical Conductivity
  • Applied Like House Paint
  • Safe, Water-Based, No VOC’

Ideal Uses

  • Whenever a high-emissivity/blackbody coating is required
  • Providing faster heatup/cooldown times for furnaces, saving energy and enabling faster throughput (increased production)
  • Improves temperature uniformity in furnaces, allowing more evenly treated parts
  • Forming highly refractory Zirconia-based coating on surface
