Generally speaking, thermoplastic road marking paint has strong adhesion and anti-cracking ability, and can effectively resist wear on sections with heavy traffic volume. Depending on different usage environments and customer requirements, the wear resistance of thermoplastic road marking paint may vary.     • Wear resistance: The wear resistance of thermoplastic road marking paint is related to the paint itself. Adjusting the production formula and adding wear-resistant fillers such as quartz sand can enhance its wear resistance.     • Service life: On roads with low traffic volume, the normal service life of hot-melt markings is approximately 1-2 years. On highways and provincial roads with heavy traffic, the normal service life of hot-melt markings does not exceed 1 year. Especially in areas such as pedestrian crosswalks at intersections on urban roads where there is severe wear from turning and braking, the service life is about 3-6 months.     • Durability: The durability of thermoplastic road marking paint is influenced by various factors, including the construction process, material quality, climatic conditions, etc. To ensure the long-term service life of thermoplastic road marking paint, it is recommended to select the appropriate formula based on different climatic conditions and strictly control the temperature and ensure uniform mixing during the construction process.

   Color-changing problem      1. During the melting process, the temperature is too high or the bottom of the thermoplastic kneader is burned. The solution is to strictly control the temperature and clean the bottom of the thermoplastic kneader before operation.      2. The paint itself is of poor quality. It is likely that the paint has deteriorated. Before applying the batch of paint, it should be tested in a professional testing department. Only after passing the test can it be used for construction.   https://www.road-markingpaints.com/sale-47322429-reflective-thermoplastic-road-marking-paint-high-reflective-road-line-marking-paint.html

Road Marking - Key Points for Thermoplastic Coating Application - Guangdong Hua Qun Traffic Facilites Co. Ltd. By Shares   [Summary Description] Currently, the road marking paints used in China can be categorized into three types: thermoplastic, water-based, and solvent-based at normal temperature. Traffic safety management departments utilize road markings to enhance traffic safety, reduce accidents, and beautify urban roads. The visibility and effectiveness of road markings depend on high-performance marking paints. With the increasing emphasis on environmental protection in modern construction and the high demands for wear resistance, skid resistance, weather resistance, and durability of road markings, low-cost thermoplastic marking paint has become the preferred choice for road marking applications in China.   Thermoplastic road marking paint utilizes the thermoplasticity of synthetic resin to enable fast drying and ensure a strong bond between the markings and the road surface. Thermoplastic reflective road marking paint typically consists of thermoplastic resin, pigments, fillers, reflective materials, and other additives. This type of paint offers excellent adhesion, long-lasting durability, strong nighttime reflectivity, quick drying during application, and good weather and water resistance. Additionally, it is cost-effective, affordable, and environmentally friendly. In its natural state, thermoplastic paint is a powder at room temperature and contains no volatile solvents. During application, it is heated to a molten state and then applied to the road surface using specialized equipment. It solidifies into a film through physical cooling. The thickness of thermoplastic markings typically ranges from 1.0 mm to 2.5 mm. The paint contains reflective glass beads mixed into it, with additional beads sprinkled on the surface during application to enhance nighttime visibility. These markings provide excellent nighttime reflectivity and have a long service life. Based on the estimated demand for various road marking paints in highway construction with high traffic volumes, thermoplastic markings generally last 2–3 years under normal conditions.   At room temperature, thermoplastic road marking paint is a solid powder. During construction, the paint is loaded into a melting kettle, and the temperature inside the kettle is controlled between 180°C and 210°C. The paint is stirred while melting, and once it reaches a molten, flowing state, it is transferred into the insulating hopper of the marking machine. The molten paint is then introduced into the marking hopper, where it is kept at an appropriate temperature to maintain its molten state. Before marking, a pre-marking machine is used to mark the positions. The primer is applied using a primer machine according to the design layout. After the primer has fully dried, the marking paint can be applied. When marking begins, the marking hopper is placed on the road surface. Due to the gap between the hopper and the surface, when the marking machine moves forward, the paint flows automatically and evenly spreads a neat line. The glass bead applicator automatically and evenly spreads a layer of reflective glass beads over the marking. Key Points for Thermoplastic Road Marking Construction: Temperature Control during Melting: The temperature during the melting process should be maintained between 180°C and 220°C. After melting, the paint should be stirred slowly and kept at the proper temperature for 3-5 minutes before it is applied. This ensures that the thermoplastic road marking paint performs optimally. Weather Conditions for Application: It is recommended to apply the paint when the temperature is above 0°C to ensure a clean, dry working surface. For high-temperature construction, the material temperature can be appropriately increased. Primer Treatment: Leave enough time for the primer to fully dry before applying the marking paint. New Cement Pavement: For newly finished cement roads, it is advisable to delay marking for at least three months or to conduct two primer treatments. Otherwise, the markings are likely to peel off. High-Traffic Roads: On roads with heavy traffic, after applying the primer, place warning cones to avoid the wheels running over the primer, which could remove it and leave dust behind. If the material temperature is below 180°C, the petroleum resin may not stretch properly, affecting the paint's fluidity. This may cause issues such as fraying on the markings, rough edges, or excess paint, which will affect the appearance of the markings. Furthermore, low temperatures can weaken the adhesion of the paint to the road surface by limiting the extension of the petroleum resin molecules. Reasons for Slow Drying of Thermoplastic Paint: Ambient Temperature: The standard ambient temperature for drying is 23°C. At this temperature, the drying time of the thermoplastic paint is less than 3 minutes. If the ambient temperature exceeds this value, the drying time will increase accordingly. High Surface Temperature: When the surface temperature is high, such as in summer on asphalt roads, the temperature can exceed 60°C. If the surface temperature is still high after the markings are applied, the paint will not cool down, causing the markings to remain undried. This issue is most noticeable during the daytime (around 11 AM to 4 PM), especially in the middle of the road, where there is longer exposure to sunlight and slower cooling. Density of the Paint: The density of the marking paint itself can be an issue. Excessive use of leveling agents and other additives can improve the flow of the paint, reduce costs, and lower the softening point of the thermoplastic paint, which causes it to gradually soften and dry more slowly.  

The HUI-HE High Speed Way is a China government project in 2021, which used our thermoplastic paint for road line marking. It was well received by the government.
