Green Glow in the Dark & UV Powder - Zinc Sulfide

The first generation of glow powder zinc sulfide has been widely used for many decades from making glow in the dark toys, novelties, body paint, soaps etc. It has a quick charge under any UV light source and glows for just under an hour. It can be recharged to glow 1,000's of times over 10 years. The daylight color of this powder is a pale green with a green glow in the dark and under a black light.

If you are looking for a good glow of over an hour then this is not for you. We offer many strontium aluminate products that is the latest generation of glow pigment for extruding, paints, resins, epoxies etc that glows in the dark for up to 40 hours.
