Our photochromic pigment powder changes color when exposed to sunlight or UV rays, and reverts to its original color when sunlight is blocked. After absorbing the light energy from the sun, the molecular structure is changed, which causes the color absorbed to appear. This effect is reversed when the light stimuli are dimmed or blocked (aka color changes back when you block the sun or go indoors).
All our photochromic pigment powders are encapsulated which means you can use them to make photochromic paint, inks, resin epoxy, water-based mediums, plastic, gels, acrylic and so much more without damaging the pigment or drying out the medium.
Pigments can appear transparent in a clear medium with a lower powder mixing ratio. These photochromic pigments can be used for a variety of applications!
