Answers to FAQ – The Minimox® Process

  • The alloy surface should be clean of oils and particles. A machined surface is optimal.
  • Apply by dip or spray. Dipping is strongly recommended. If there is sufficient oxygen and elevated temperature during service, no other processing is required.
  • Protection occurs after heating in air; it is not a clear coat.
  • For systems that require preoxidation, the temperature is set by the alloy and end use.  For aluminum alloys, it may be 250°C, while for nickel alloys, the oxidation temperature may be 1000°C. The active ingredients in Minimox are stable well over 2000°C.
  • Some applications may require periodic respraying.
  • It is effective on stainless steel, nickel alloys, titanium alloys, magnesium alloys, and superalloys.
  • It is not effective on low carbon steels.
  • Higher chromium tool steels can be processed.
  • Complicated geometries can be treated, including inside tubing, mesh, and honeycomb.

After coating and air drying, the treated surface is fairly robust and can withstand handling.
