Reflective road paint beads play a necessary part in traffic safety because of their retro-reflective properties. This property lets in the motorist to truly see the pavement line markings greater truly at night and in moist conditions. When a car's headlight beam shines on a pavement marking that is integrated-embedded-saturated with reflective glass beads powder, the line stripes light up and come to be plenty less complicated to see at night. This effect is called the retro-reflection. Glass beads for road marking paint can be divided into two types: the intermix type and drop on, and the intermix type, which should be added directly in the road marking paint, and stir together. While, the drop on type is drawn in the pavement marking, not directly sprayed over the dry coating reflective micro glass beads.
