Thermoplastic CoatingWhat are the components? The components of thermoplastic road marking coating are as follows: petroleum resin is a derivative of petroleum, and thermoplastic road marking coating utilizes the thermoplastic characteristics of synthetic resin to make the coating quick-drying, using its thermoplasticity to ensure the marking has tightness. Coloring pigments are essential for thermoplastic coatings, as the common thermoplastic coatings are yellow and white. Adding glass beads to the coating improves the visibility of the markings at night, as glass beads can refract, reflect directionally, and gather light. Additives are important elements for the anti-pollution and plasticity of thermoplastic road marking coatings.

　　Road Marking Construction CoatingManufacturer: What is the construction sequence of thermoplastic coatings?

　　Construction steps for thermoplastic coatings: 1. Surface cleaning: Sweep the ground before construction to remove dust, suspended slurry, and moisture. 2. Marking: Since the construction of thermoplastic road marking coatings is generally a one-time formation, the route and patterns need to be marked before construction. 3. The conventional construction equipment for thermoplastic coatings includes a dryer, a melting kettle, and a hand-pushed line marking machine. Before marking, the coating needs to be heated and melted in the melting kettle. 4. Applying the coating: After the coating is melted, install the line marking machine along the marked production line to allow the melted thermoplastic road marking coating to flow out, while spraying glass beads with a self-weight sprayer onto the coating film. 5. Modification after marking: Modifications should be made before the thermoplastic coating completely cures, removing markings that do not meet requirements, excess coating films, and checking dimensions, thickness, and distribution of glass beads.

　　Road Marking Construction Coating Manufacturer: What is the reason for thermoplastic coatings not being white?

　　When constructing thermoplastic coatings, attention should be paid to controlling the temperature, usually cooking between 180 and 220 degrees. After reaching a normal 200, insulation treatment should be performed. Before putting the thermoplastic coating into the line marking vehicle, the filter must be cleaned thoroughly. It is essential to prevent damage to the filter. When using thermoplastic coatings that have been left overnight, the mixture must be uniform, and adding titanium dioxide to the coating can improve the whiteness of the markings.

　　Road Marking Construction Coating Manufacturer: What are the advantages and disadvantages of thermoplastic coatings?

　　Thermoplastic coatings have better wear resistance than conventional solvent-based markings, lasting over a year in high traffic areas. The glass beads dispersed within the markings can reflect light. However, due to the main raw material of thermoplastic coatings being C5 petroleum resin, they are significantly affected by temperature changes. In summer, the markings can easily become sticky and attract dirt due to high temperatures, especially in heavily polluted cities where the markings can turn black.
