Thermochromic Pigments and Coatings for your Customised Project

Our thermochromic colours can be used for a variety of applications. You can make warnings visible by changing the colour, e.g. on hot surfaces, or integrate the colour change into your product as an interesting gimmick.

• Our liquid crystal pigments change colour at 25-30ºC when rubbed or touched.
• Our thermochromic inks are used on labels and packaging to cause a colour change on cooling (clear to colour at 15ºC)
• Thermochromic inks that are activated by touching will temporarily disappear when rubbed or touched;(colour to clear at 31ºC)
• Thermochrome pigments for high temperatures are designed to change colour just below the pain threshold, alerting the user to a safety risk or quality issue - too hot! (colour becomes transparent at 47 ºC)

The activation temperatures range from low temperatures to normal body temperatures to high temperatures.

The thermochromics are available as a finished ink, as a pigment or as a liquid crystal screen printing ink. Colours and temperatures can be adapted to your individual application. The temperature range for which thermochromic inks can be used is: -10°C to 69°C.
