Thermochromic dyes in refractory mold coatings provide a change in color corresponding to a change in temperature to indicate when a coating is dry.
While these features are not easily assessed with thermochromic dyes, the use of a non-contact infrared thermometer technique provided the following key benefits:
Because of the problems associated with thermochromic dye assessment of mold dryness, the use of a non-contact infrared thermometer was explored to record the thermal profile of the mold coating application (Fig.
