    Introduction of Photochromic Dye

    Photochromic dye is a special small molecule material that can change color under ultraviolet light, and it is white or off-white powder. When the dye is excited by ultraviolet irradiation, the molecular structure changes, resulting in a color change. When the ultraviolet irradiation is removed, the molecular structure returns to its original color. 

    The dye itself does not change color after ultraviolet irradiation, and needs to be dissolved in the medium (such as organic solvents, resins, plastics) to be photosensitive and discolored; Soluble in media of different polarities, the color change will be different. The product is colorless in the dark or indoor light source environment, and the color of the product is quickly shown under ultraviolet light or sunlight, and it becomes colorless again when isolated from ultraviolet light source.

    Solubility of Photochromic Dye

    Dyes can be soluble in most organic solvents, such as ethyl acetate, butyl acetate, tetrahydrofuran, acetone, benzyl alcohol, toluene, styrene, etc.


    Photochromic dyes have less solubility in more polar solvents, greater solubility in less polar or non-polar solvents, and do not exhibit photochromic properties such as acetonitrile in individual solvents.


    Advantage of Photochromic Dye

    1. Intelligently sense the strength of ultraviolet rays
    2. When there is no ultraviolet light, it is transparent. Dark under ultraviolet light, and effectively blocks ultraviolet rays.
    3. The color is uniform under ultraviolet light.


    Application of Photochromic Dye

    1. Coating: Suitable for all kinds of surface coating products, including PMMA paint, ABS paint, PVC paint. 


    2. Inks: Printing of various materials, including fabric, paper, synthetic film, glass, etc. 


    3. Plastic products: suitable for all kinds of plastic PP, PVC, ABS, silicone rubber and other materials injection, extrusion forming.
