    Thermal Dust 72F is a thermochromic pigment.  This pigment, which activates at 72F, is "cold activated" rather than heat activated, and it GAINS color (colorless to color) at 72F and colder.  Ultra Thermal Dust 72F changes from one color to another color!

    Thermal Dust is great for use in many clear or neutral mediums, including resin, epoxy, paint base, lacquer, glue, gel, varnish, clear coat and other bases.  

    Mixing Ratio:  Use 1 gram for 1 fluid ounce of a clear-drying base.  

    NOTE:  Thermal Dust is heat sensitive and can change color several times over, however, keeping Thermal Dust in the sun over time will create a "sunburn" on the pigment eventually causing it to cease changing color.
