Color change to another color thermochromic Pigment

Color change principle: One color changes another color, such as DF-207(red to yellow), the temperature below 31 degrees is displayed red, and the temperature above 31 degrees becomes yellow. When the temperature drops below 31 degrees again, the color returns to red. The color can change repeatedly depending on the temperature.
Color-changing effect from color A to color B can be obtained by matching color between thermochromic pigments and ordinary pigments

The color-changing principle and structure of reversible thermochromic pigments:
Thermochromic pigments are microcapsules that repeatedly change color as the temperature rises or falls.
Reversible thermochromic pigment is prepared by electron transfer organic compound system. Electron transfer organic compounds are a kind of organic hair color system with special chemical structure. At a specific temperature, the molecular structure of the organic matter changes due to electron transfer, thus achieving color transformation. This color-changing substance is not only bright in color, but also can achieve color change from the state of “colored === colorless”, “colorless === colored” or “colored === colored”, which is not possessed by heavy metal complex salt complexes and liquid crystal reversible temperature-sensitive color-changing substances.
Microencapsulated reversible thermochromic substance is called reversible thermochromic pigment (commonly known as: thermochromic pigment, thermochromic powder or thermochromic powder). The particles of this pigment are spherical, with an average diameter of 2 to 7 microns (one micron is one thousandth of a millimeter). The inside is a color-changing substance, and the outside is a transparent shell about 0.2 to 0.5 microns thick that can neither dissolve nor melt, which protects the color-changing substance from erosion by other chemicals. Therefore, it is very important to avoid damaging this shell in use.

Uses: Slime creation, crystal clay creation, glue creation, ink, paint, color-changing nail polish, injection molding, silicone, printing and other wide applications.
