In the increasingly competitive road marking paint market, the durability, reflective persistence and overall cost of the product directly determine the core competitiveness of the product. Barium sulfate, as a key filler, is far from being a simple filler; rather, it is the core for enhancing product performance.
The three core roles of barium sulfate in marking paint
1. Excellent wear resistance directly extends the service life
Road markings bear the heavy pressure and wear of heavy traffic every day. Our natural barium sulfate, with its high hardness and dense particle structure, can significantly enhance the wear resistance of the paint film. This means that the wear value of the marking paint is lower, its service life is longer, and it creates better long-term value for customers.
2. Stable chemical inertness, fearless of acid rain and climate challenges
The marking lines are exposed to the outdoors for a long time, especially in industrial areas where acid rain occurs frequently. The chemical corrosion resistance of the coating is of vital importance. The natural property of barium sulfate, which is insoluble in water and acid, ensures that the marking paint can maintain color stability for a long time in harsh environments, effectively resist powdering, yellowing and erosion, and keep the appearance as good as new for a long time.
3. Excellent dispersibility and leveling property ensure construction efficiency and reflective foundation
Our barium sulfate products feature precisely controlled particle size distribution (D50) and extremely low impurity content. This ensures its excellent dispersibility in the resin system, endowing the coating with superior construction leveling property and forming a flatter and smoother paint film surface. A smooth surface is the prerequisite for glass beads to be evenly and firmly embedded, thereby achieving efficient and long-lasting reflection.
