Ri 1.7

Suitable for various hot-melt road markings, two-component coatings, and all types of flat and structural road markings, this product can be used in combination with other reflective elements to provide solutions for road markings of different performance levels, meeting the initial and sustained retroreflective performance requirements of high-performance markings. Its unique formulation and surface treatment process enhance the retroreflective performance of the markings, increase the adhesion between glass beads and the marking material, and improve both the wet-state reflectivity and anti-fouling properties of the markings.
