Glow in The Dark Powder Daytime Visible Chartreuse Pigment 10 Grams

10G of 35um Glow in the Dark YELLOW Solvent Pigment Powder. SALES PRODUCT does NOT include the glass jar, comes in a clear plastic tub. PLEASE BE AWARE this tub closes VERY tightly- you do not want a face cull of powder when you open it. PLEASE NOTE: SrA12O4:Eu When activated with a suitable dopant (Europium) then it takes on a different structure and becomes a Phosphorescence emitting its glow. It now requires UV in the higher spectrum to charge the crystals and make them GLOW. UV Ultra Violet light is the electromagnetic radiation from Sunlight with a wavelength shorter than white light. In summer the paint supercharges on the emitting UV rays from sunlight and makes the paint REALLY POP, however in the winter months when there is limited UV in the suns rays then it is harder to charge the paint. We use UV Black lights to help charge the paints in the winter months. These are specially designed BLACK LIGHTS you can purchase from stores etc. We DO NOT give glow times on our products because we cannot guarantee this, there are too many factors involved, some we have already spoken about. This paint is daytime invisible, meaning it is an off-white color during the day & glows YELLOW in the dark. ALL PHOTOS/IMAGES ARE PROPERTY OF GLOMANIA & PROGLOW USA
