Road marking glass beads are used to guide road users in the dark due to the presence of glass beads on its surface reflecting the lights of cars, motorcycles and bicycles. The glass beads reflect the headlights of the vehicle to the driver, acting like a mirror. In order to ensure a high level of visibility in all weather conditions, Sicheng has developed different glass bead ranges suitable for each type of application. Beads for horizontal road marking can be either dropped on the product when it is applied in situ – “Drop-on”; and/or pre-mixed with the product during the manufacturing stage in the factory – “Premix”. Visibility by day as well as during the night in various weather conditions, anti-skid performance, wear resistance and durability are essential characteristics of good road markings. Sicheng produces glass beads for all kinds of road marking products such as solvent based- and waterborne paints, thermoplastics and 2 component systems.
