Luminescent paints are special types of coatings that glow in the dark after being exposed to light. They contain phosphorescent materials, which absorb light energy and then slowly release it, creating a glowing effect. These paints are often used for decorative purposes, safety signs, and in art projects. The glow from luminescent paints can last for several hours, depending on the quality and thickness of the application. They are available in various colors and can be applied to different surfaces, including walls, wood, and metal. Popular uses include children's rooms, nighttime safety markers, and art installations.
