Thermochromic Technology

1. The color-changing principle and structure for reversible thermochromic pigments

Thermochromic pigment is a kind of microencapsulation that can change colors in a repeating mode when the temperature goes up and down.

Reversible thermochromic pigment is produced by electron-transfer organic compounds. Electron-transfer organic compounds is an organic luminescence system that is featured with special chemical structure. In certain temperature, when the electrons transfers, the molecule structure of this kind of organic substance will change, thus triggering the change of color. This kind color-changing substance is not only featured with strong color, but also can realize the color change from “colorful to transparent” state to “transparent to colorful state”. This kind of property is not possessed by reversible thermochromic substances featured with liquid crystals and heavy metal complex salts.

There are 15 Primary colors for reversible thermalchromic materials in their colored state:

Except for basic color, we can also configure different colors that change from one to another according to customers’ requirements:

Such as: brown to red, purple-blue to light red, purple-red to light blue, blue to yellow, red to yellow, purple to red, purple to blue, green to yellow, orange to yellow, ect.

2.Regular temperature for changing color: 18℃、22℃、31℃、33℃、45℃、65℃. Other temperatures for changing color need to be customized.

3.Thermochromic inks can change colors repeatedly when the temperature goes up and down. (Take 31℃ red color as an example. The color will be transparent when the temperature is above 31℃, and red when the temperature is below 26℃)

4.Thermochromic inks/oil paints can be used in products painting, mesh-printing. The products are designed in response to the need of color change at high temperature or low temperature. The materials are generally used in products related to human body temperature test or change of water temperature. They can also be used to prevent counterfeiting.
