Road Marking Paint
Road marking paint is a kind of chemical coatings specially used to marking and painting road traffic signs and lines. According to the construction process and its own characteristics, marking paint is generally divided into three categories, such as thermoplastic paint, cold marking paint and two-component marking paint.
Thermoplastic paint has significant characteristics of fast drying, thick coating, good wear-resistant, long life service and outstanding reflection stability. This paint can be used to marking screeding type flat line, spray-type anti-slip lines, convex vibrating lines and extrusion bumped lines. During the marking construction process it generally requires a heating device, called preheater, to melt powder paints into liquid state, ready for machine painting. Cold marking paints are usually two types, water-based paint and solvent-based paints, suit for asphalt and concrete pavement line marking. Cold paints need no heating, using the spraying process. The painting process is relatively simple compared to thermoplastic paints and two-component marking paints. Two-component marking paint is composed of A, B two parts in a certain mixing ratio coated onto the road surface. Without heating during construction process, by crosslinking reaction, it forms into a durable coating on the road surface, which has strong adhesion to the road surface and reflective glass beads. Two-component marking lines have outstanding characteristics of solid coating, dense internal structure and long service life. In the snow areas, it can avoid the damage caused by shoveling snow. |
