Once light dims, the phosphors in the paint radiate, emitting light until they lose the charge they gathered up in the daylight. How long do glow in the dark paints last? Acrylic paints are chemical-based and are made up of colorful pigments suspended in an acrylic polymer emulsion. They produce more fumes than water-based paints and are less eco-friendly. Acrylic paints tend to adhere better to surfaces than water-based paints, but clean up is more difficult because paint thinner is typically required for cleaning brushes, spills, or splattering that may occur. They are more appropriate for outdoor projects since they’re able to expand and contract with changing temperatures and humidity levels. Another reason they are better suited for outside work is that they’re fade-resistant, meaning UV rays won’t cause them to discolor over time. What to Consider When Choosing the Best Glow in the Dark Paints The latest generation of the radioluminescent materials is based on tritium, a radioactive isotope of hydrogen with half-life of 12.32 years that emits very low-energy beta radiation. The devices are similar to a fluorescent tube in construction, as they consist of a hermetically sealed (usually borosilicate-glass) tube, coated inside with a phosphor, and filled with tritium. They are known under many names – e.g. gaseous tritium light source (GTLS), traser, betalight.
