Reflective® A special powder made of glass particles (reflective powder) in white or gray is combined, for example, with paint that covers knitwear or fabric. This creates a durable, uniform material that can be used as inserts in clothing or treated as a base material for, for example, a jacket. Reflective paint can also be used to create prints. A reflective element, like glass, in contact with an intense beam of light reflects it at the same angle or in a diffused manner, making it more visible. The effect of reflection, its intensity, increases when there is semi-darkness or darkness.
