High Retro-reflection Dual-Coated Glass Beads During the production of regular beads, coated them with different kinds of coatings to increase the moisture-proof and adhesion characters, so that the durability of beads and reflectivity can be increased. These beads are coated with a special coating materials, during the manufacture of the glass beads, which will improve the characteristics of moisture-proof and adhesion of glass bead. In the way, the life cycle of the glass beads can be prolonged and this enhances the beads reflectivity in a rainy night. These beads are usually used in white or yellow line-construction of highway.
