Color change and color development with temperature fluctuations! Temperature-sensitive materials that enable a wide range of color expressions.
"Thermal Color" is a thermochromic material based on compounds that change color at specific temperatures, which can be formulated as pigments or paints (ink). The Thermal Color KT series has a wide temperature range of -20 to 60°C and can be manufactured at set temperatures (every 5°C). It can be used for frozen food management labels, heating hazard indication labels, and more. 【Features】 ■ Allows temperature measurement simply by applying it to an object ■ Easy to handle, similar to regular paints ■ Enables direct visual measurement of a wide range of temperature distribution ■ Indicates the maximum temperature reached ■ Can also serve as a protective coating for the objects and plants it is applied to *Please feel free to contact us for more details.

This is an image of using thermal color KT in a cup holder. It fades with an increase in temperature and regains color when cooled. This phenomenon is reversible, so it occurs repeatedly.
