Candy Glow in the Dark - Water based paint for fabric, metal, glass, tiles, and plastic - The glow in the dark paint only can see when the surrounding area are dark. - Currently only yellow green is the longest glow time - around 8 hours after absorbing 1 hour light. It can be even brighter when it is under spot light - You can mix your own paint. In that way you can maximize the amount of glow. Note: The more powder added, stronger the glow - We are using Alkaline Rare Earth Metal Silicate-Aluminate Oxide Europium Doped. - It is NEXT GENERATION long persistence phosphorescent pigment ( alkaline earth aluminate activated by rare earth ions). - They can be recharged over and over indefinitely. - The brightness and length of persistence time is ten times than those of conventional phosphor zinc sulfide found in your local stores. - It is ten times brighter and glows ten times longer than the sulfide type Photoluminescence Materials.
