Luminescent paints are special types of coatings that emit light after being exposed to a light source. They contain phosphorescent materials that absorb energy and then release it slowly, creating a glow in the dark effect. These paints are often used for safety signs, decorative items, and art projects. The glow from luminescent paints can last for several hours, depending on the quality and type of paint used. They are available in various colors and can be applied to different surfaces, including walls, wood, and metal. Popular applications include glow-in-the-dark stars for children's rooms and safety markings in low-light areas.
