Color Changing Effects

These aqueous concentrates and inks are thermochromic pigments which develop color when heated above a given activation temperature.

They are a combination of Leuco Dyes, Color Developers and Melt Materials all blended together and then micronized to reduce particle size. This is then combined into a carrier forming an aqueous concentrate which changes from off white to a color permanently when heated above its rating. As temperature increases, color density increases.

A Process Control Visual Alert For:

  • Metal Fabrication
  • Annealing
  • Surface Temperature
  • Machinery
  • Quality Control
