Glow Inc.'s Zinc Red Glow in the Dark Powder is a fully water compatible pigment that glows a deep red, almost the color of blood. It can be used in a variety of mediums including plastic, paint, fiberglass, concrete, wax, and gel. Like all Zinc Sulfide powders, Zinc Red has a strong sulfur odor in its pigment form. This odor generally subsides when mixed into a medium.

Zinc glow in the dark pigments are fairly stable and can exist in almost any medium. They are slightly soluble in water, but this does not appear to make a noticeable difference in most applications. This makes them a great choice for use in mediums that contain water or acid.
Other color pigments in the medium will sometimes shield the glow pigments, preventing them from charging as fast or glowing as bright. Therefore, we suggest clear mediums when possible. Ultraviolet filters in mediums may block the ability for glow pigments to charge. This can both increase charge time or lower brightness depending on the quantity and quality of the ultraviolet filters. Most paint manufacturers will have special order product SKUs for non-ultraviolet filter versions of their paint.
Warning: Many customers try to create a 'cheap' glow in the dark paint by purchasing clear paint from a local source and the raw glow in the dark pigment from Glow Inc. The majority of these customers end up frustrated. If you need a paint, we suggest that you either purchase our premixed paints or follow the instructions in our how-to articles for specific projects.
