Zypcoat MAO

Zypcoat MAO is a water-based coating of 100% Magnesium Aluminum Oxide (MgAl2O4) that is non-reactive with molten Aluminum-based alloys, particularly Magnesium-containing melts.  Zypcoat MAO  is usable to over 1500 C in all atmospheres.


Key Attributes

  • Non-reactive with molten nonferrous/ferrous metals/alloys
  • Good abrasion resistance and chemical resistance at high temperatures
  • Use temperature of over 1500 C in all atmospheres
  • Water-based, easy to use and cleanup

Ideal Uses

  • Molten metal processing/transport
  • Applications that require temperatures greater than typical aluminum processing
  • Barrier coating to prevent diffusion, reactions, and sticking of parts during heat treating
  • Materials requiring zero Boron contamination (aerospace/nuclear areas)
