Brazil Reflective Glass Beads Pavement Markings

Thermoplastic marking paint is mainly composed by synthetic resin, glass beads, pigments, packing materials, additives, etc.

Synthetic resin has thermoplasticity, make the hot melt coating fast dry and strong adhesive to the road surface.

Additives in the paint can increase the plastic of the coating, and make it resistant to subsidence, pollution and color fading.

Pigments: the common colors of road lines are yellow and white. White pigments are mainly titanium dioxide, zinc oxide, and lithopone, while yellow pigment is mainly het-resistant yellow lead.

Packing materials, as filling added into the paint, ensure mechanical strength, wear resistance, and color of paint coating. The particle size will affect liquidity and precipitation, as well as the surface processing.

Glass beads are added in order to improve the identification of lines at night, to improve the brightness and durability of the marking. Glass bead is colorless and transparent ball, has function of light refraction, focusing and directional reflection. Glass bead mixed in the coating or dispensed throughout the coating surface can reflect car light back to the driver's eyes, thus greatly improving the marking visibility.
