PHOTOCHROMIC (Colour Changes on Sunlight )

PHOTOCHROMIC (Colour Changes on Sunlight )

The Photochromic Product changes colours when exposed to sunlight and revert to its original colour when the sunlight is dimmed or blocked. After absorbing the energy of sunlight, its molecule structure is changed which causes its absorbed wavelength to be changed allowing the colour to appear. The photochromic dye reacts to sunlight only when dissolved in a binder, Polarity of the medium is directly related to the colour.
