Thermal Dust! - Colorless to Orange (72F)/(22C) Cold Activated
Thermal Dust 72F is a thermochromic pigment. This pigment, which activates at 72F, is "cold activated" rather than heat and gains color at 72F and colder.
Thermal Dust is great for use in many mediums, including resin, epoxy, paint base, lacquer, glue, gel, varnish, clear coat and other bases.
Mixing Ratio: Use 1 gram for 1 to 2 fluid ounces of base. You can mix 10 grams to 10 fl oz and dilute up to 20 fl oz of 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.
