All-weather reflective microcrystalline ceramic beads,is not the normal reflective glass beads, it is with better reflective effect especially in wet night road.
It is ceramic beads, is a new generation of reflective material referring to home and abroad similar products and depending on independent research and development of universities and colleges. Using method is similar to the reflective glass beads. If we use the paint with the reflective glass beads, the line-marking will be very clear on a rainy night or even submersed in water. The line-marking using microcrystalline ceramic bead is called as all-weather reflective marking.
