photochromic powder

This photochromic pigment shifts from a pale or clear state to a deep, rich color within one second of direct sunlight, then reverses indoors. Fine particle sizing makes it a workable printing pigment for inks, screen printing, and surface effects, with both clear-to-color and color-to-color options across purple, blue, red, green, and more. As a UV activated pigment, it stays dormant until sunlight or UV hits the substrate — no external power, no coating, just light.

KT-PMC-14-BA is a Blue photochromic pigment in the fine 1–10μm particle size range — a UV-reactive single-color activated grade that appears pale or near-colorless under standard indoor lighting and shifts to a deep blue within approximately one second of exposure to direct sunlight or UV irradiation. 

Photochromic Pigments change color in response to UV light exposure, transitioning from a pale or near-colorless state indoors to a saturated color within seconds of UV exposure, then reversing when the UV source is removed. The KPMC series is available in multiple colors with a particle size of 1–10 µm, suitable for inks, coatings, plastics, and cosmetic formulations where a UV-activated color response is required.
