Special Temperature Sensitive Pigments

  Special Temperature Sensitive Pigments 【Introduction】        Anti-forgery temperature sensitive pigments is also called thermochromic pigments or heat-sensitive color-changing pigment.  It changes color with the temperature changing. 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).There are reversible thermochromic powders and irreversible thermochromic powders. Thermochromic pigments can be divided into low temperature color-changing powder, body temperature color-changing powder and high temperature color-changing powder.       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…
