After coating the glass beads with thermoplastic coating, the speed dry character should have a short time (less than 5min), regardless of the climate. The general thermo plastic road reflective coatings have good speed drying (hardening) performance, harden quickly in the cold season, and slow in the warm season. The solidification of the film will be twisted, the surface flow is poor, and the fixed quality of the glass beads is also poor. When the film curing is slow, not only the glass beads will sink into the coating, which will reduce the reflective ability, but also delay the opening traffic time and reduce the traffic capacity. To this end, it is usually to reduce the temperature of the coating in the melting state, so as to shorten the curing time.
