Interval Thermochromic Material
A. Principle
By using microencapsulation technology, the leuco-dyes, color developers, and temperature controllers are encapsulated and made into pigments.
The color appears as heating around 30~50°C, and becomes colorless when cooling under 30°C or heating over 50°C.

D. Notice：
1. Avoid using polarity solvents such as alcohols (methanol, ethanol), ketones (acetone, butanone) …etc.
2. Processing temperature should not exceed 230°C.
3. Thermochromic materials and products should be sealed and kept in dark to prevent UV aging that will affect color-changing function.
