Thermolock is a heat sensitive color changing pigment that performs a semi-permanent color change in which a color disappears and is locked in at or above a threshold temperature.

Additionally, the original color will not return under ordinary, daily conditions, but only if the temperature is lowered dramatically. Some possible uses may include temperature control indicators as well as security products and sensors.
