1.Brief Introduction
Color changes of thermochromic pigments are induced by temperature change. The pigments are composed by microcapsules that change colors reversibly. When temperature rises to a specified temperature, the color starts fading and back to the original color as the pigment is cooled down.
2. Products Feature
A. Nine Standard Colors

B. Temperature of color changes
When the temperature is increased to a specify temperature, the color start fading to colorless. The specific temperature of the color changes can be assigned at a temperature between -15°C to 65°C. The sensitivity of color changes is within 2°C to 10°C. The temperature of color change set under 33°Chas fine sensitivity and those over 33°C are duller.



Example 1. BT-22 indicates the blue thermochromic pigment starts to change its color when it is heated to about 18°C and becomes completely colorless at 22°C. Conversely, the color starts to reveal when the temperature is decreased. It's recommended to applying this for cold drinks.
Example 2. OT- 31 indicates the orange thermochromic pigment starts to change its color when it is heated to about 29°C and becomes completely colorless at 31°C. Conversely, the color starts to reveal when the temperature is decreased. This product is most suitable for products, which change colors at body temperature.
Example 3. RT- 43 indicates the red thermochromic pigment start to change its color when it is heated to about 40°C and becomes completely colorless around at 43°C. Conversely, the color starts to reveal when the temperature is decreased. It could be used as a caution for hot drinks.
