This is a microcapsule product with photochromic dye which changes its color by light. The photochromic dye causes color change reversibly by light. When light is blocked, it has its original color.
Since it is very sensitive to the environment, it becomes encapsulated in micro synthetic resin with several µm to hundreds µm in diameter for protection and stability increase.
Principle of color change
When photochromic microcapsule is exposed to sunlight like UV rays, the structure of the internal substance of the capsule changes and thus it has color.
And when light is blocked, the internal substance of the capsule returns to its original state, and consequently its color disappears.
ChromaLux Bichrom Series is a reversible photochromic microcapsule that its color lightless state changes to other color once exposed to light.
Since it is very sensitive to the external environment, it becomes encapsulated in micro synthetic resin with several µm to hundreds µm in diameter for protection and stability increase.
The substance causes the change of color by light. When it is exposed to ultraviolet rays (sunlight), the structure of photochromic molecules reversibly changes, and thus the change of color occurs.
It is mainly used for plastic and textile processing, Five colors are available for sales.
