Thermochromic Liquid Crystals are highly temperature sensitive, changing through many colors. As temperature is increased, Liquid Crystals go through color changes from red to green to blue. Liquid Crystals are reversible and can be used repeatedly.

Liquid Crystal technology reacts to fluctuations in temperature. They can be formulated to react to temperatures between -30°C (-22°F) and 120°C (248°F) and react to changes in temperature as small as 0.1°C (0.2°F). They are also accurate up to +/- 1°C, and if stored and used correctly, they can remain functional for several years.

Temperature Range:
-22⁰F to 248⁰F

Color Change (Two Types):
Sequential Color Change Red, Green and Blue
Single Color Change Above or Below a Transition Temperature

Printed Sheets
Water Based Sprayable
