Photochromic pigments change from one color to another and colorless to color when exposed to sunlight or ultraviolet (UV) light, and reverts to its original color when sunlight is blocked. After absorbing the energy of sunlight or UV light, it’s molecule structure is changed, which caused its absorbed wavelength to be changed allowing a color to appear.

Photochromic pigments can be used in wide range of industries, such as paints, inks, adhesives, plastics, and etc… We provide aqueous slurry, micro encapsulated powder, and master batches.
