phosphorescent pigment

Kolortek's glow in the dark pigment series delivers reliable afterglow across a broad color range — from yellow-green and blue-green to orange-red and violet — making it a practical base material for coatings, printing inks, nail products, and safety-marking applications. Available in both strontium aluminate and zinc sulfide formulations, with water-based compatible grades included, these powders integrate cleanly into a wide range of carrier systems. Whether you're sourcing luminous pigment powder for decorative cosmetics or functional safety applications, the lineup covers the particle size and chemistry options most formulations actually need.

KT-GYG03DSA is a Yellow Green zinc sulfide (ZnS) phosphorescent pigment in the 20–40μm particle size range — the cost-effective glow-in-the-dark option in the Kolortek range for applications where a short-duration afterglow is functionally sufficient and the price premium of strontium aluminate is not warranted.

KT-GBG02 is a Blue Green strontium aluminate phosphorescent pigment in the coarse 65–75μm particle size range — a glow-in-the-dark pigment that absorbs ambient light (sunlight, fluorescent, LED) during exposure and releases it as a sustained blue-green glow after the light source is removed.
