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.

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. |
