Comparative Study on the Performance of Hot-Melt Marking Paint and Traditional Solvent-Based Paint

In the selection of road marking materials, hot-melt coatings and solvent based coatings are two widely used technical routes. As TOP ROAD Transportation Technology Co., Ltd., which has been deeply involved in the industry for many years, we rely on solid practical experience and continuous product research and development to identify the core differences between the two and help our engineering team make more scientific choices based on actual needs.

Hot melt coatings exist in solid powder form and need to be heated to a molten state before application. Its advantage lies in the significant thickness of the formed markings, outstanding wear resistance and durability, especially suitable for main roads and highways with high traffic volume and wear strength. The surface of the marking can be evenly spread with glass beads, providing excellent continuous reflective effect and strong guarantee for night driving safety. At the same time, the material has a fast curing speed and can be opened to traffic within a short period of time after application, effectively reducing the impact on existing traffic flow.

In contrast, traditional solvent based coatings (often referred to as “cold coats”) can be applied at room temperature and rely on solvent evaporation to form a film. Its main characteristics are convenient construction, relatively economical cost, and strong adaptability to grassroots road surfaces, especially suitable for scenarios such as parking lots, residential roads, and old line redevelopment that do not require high durability. However, its paint film is thinner, and its wear resistance life is usually shorter than that of hot melt coatings, and the drying speed will significantly slow down in low temperature or humid environments.

From an environmental perspective, hot melt coatings, as solid materials, have extremely low volatile organic compound content, which is more in line with modern environmental protection concepts. Solvent based coatings will have solvent evaporation during construction and drying processes. TOP ROAD Transportation Technology Co., Ltd. closely follows the trend of environmental protection, and its product line meets strict environmental standards.

The choice of materials ultimately depends on the specific needs of the project: in pursuit of long-term durability and high-strength reflectivity, hot-melt coatings should be preferred; If the project budget is limited, the construction pace is fast, or the substrate situation is complex, solvent based coatings are more flexible. TOP ROAD Transportation Technology Co., Ltd., as a comprehensive supplier of marking solutions, offers high-performance hot-melt coatings and environmentally friendly solvent based coatings, with a professional team providing selection guidance to ensure that each material can play a significant role in suitable scenarios.
