Reflective Glass Beads (or  Coated) for road marking  

The reflective glass bead is necessary material for standard road paint mainly used for road marking (hot-melt paint premixing and dropping on surface), signboard, fence profile marking and handicraft bead.
After outside treatment by a high-performance organosilicon, the strong polar group on the surface of coated glass bead is transformed into non- polar group, which weakens the dust adsorption of bead surface from the air. As the specific coupling agent exists in the coated bead, the cohesive force of the tiny bead and paint is improved so as to prevent part of fine glass from depositing into paint. The coated glass bead after treatment is more predominant in the performance.
