? ? ? Anti-forgery Temperature sensitive Pigments is also called Temperature sensitive Pigments or heat-sensitive color-changing pigment. It is a kind of microcapsule-coated powder. It looks like a tinted or white powder with extremely small particles (there are also water emulsion types). It changes with the temperature. Color changes will occur.
There are varieties suitable for application in low, medium and high temperature environmental conditions.。

? ? ? There are six main types of Temperature-Changing Pigments: (1) Reversible temperature-changing achromatic: that is, there is color below a certain temperature, and it becomes colorless when the temperature rises; (2) Reversible heating and color development: that is, it is colorless below a certain temperature, and becomes colored when the temperature rises; (3) Reversible color development by cooling: colorless above 20 degrees, color when cooling; (4) Irreversible color development: colorless below a certain temperature, color by heating, but irreversible, that is, it cannot return to the state before heating; (5) Irreversible elimination Color: that is, there is color? below a certain temperature, and it becomes colorless when the temperature rises, but it is irreversible, that is, it cannot return to the state before the temperature rise; (6) Reversible interval color development, that is, it is colored between 27 degrees and 45 degrees, and below 27 degrees and Above 45 degrees it is colorless.
