The shelf life of glass beads What is the reason of decreased retroreflectivity? ---The corrosion and wear of road marking glass beads The road marking line is intact, and the glass beads are not offset, why the retro-relfectivity is decreased, come out today, let’s talk briefly -glass beads! In the natural state, the glass has a self-corrosion phenomenon, and the transmittance of glass is in a st...

Influence of Paint Temperature on Hot-melt Marking Performance The marking performance is related to the temperature of hot-melt marking paint. If the melting temperature is too high, it will accelerate the volatilization of additives in the paint, even deteriorate the paint and reduce its adhesion to the road surface. The temperature will also affect the sedimentation of glass bea...

Influence of different road types on adhesion of marking paint The adhesion between hot-melt road marking paint and road is the basis of ensuring the excellent performance of markings. The factors that determine the bonding effect between marking paint and road surface are not only the performance of paint itself and construction technology, but also the type of road surface. 1. Cement road surfac...
