PRODUCT IDENTIFICATION
Glass bead for road marking paint. Reflective glass bead are especially for road marking paints(thermoplastic,cold solvent,water-based component) to provide excellent night retro-reflectivity.Coating can improve coupling between glass beads and road marking materials.prevents sinking og glass bead to the bottom of material.
As micro beads coated with a specific coupling agent, to improve the adhesion of the coating bead and to prevent deposition of micro beads to the paint. Because of its function floatability, the use in the coating surface float, which has the largest surface area can be increased more than 30% utilization. Glass bead coating processing performance is more superior in humid environments such as rainy,foggy with its better reflective capabilities.
