Calcium carbonate is commonly used in the formulation of thermoplastic road marking paints due to its various beneficial properties and contributions to the performance of the final product. Here's how calcium carbonate is utilized in this industry:

Extender and Filler: Calcium carbonate serves as an extender and filler in thermoplastic road marking paint formulations. It helps to reduce the overall cost of the paint while maintaining volume and coverage. By replacing more expensive components, such as titanium dioxide, calcium carbonate helps to economize the formulation without compromising performance.

Opacity and Whiteness: Calcium carbonate contributes to the opacity and whiteness of thermoplastic road marking paints. This is crucial for ensuring that road markings are highly visible, especially during nighttime or adverse weather conditions. The bright white color provided by calcium carbonate enhances contrast with the road surface, improving visibility for drivers.

UV Stability: Calcium carbonate enhances the UV stability of thermoplastic road marking paints. It helps to prevent color fading and degradation caused by exposure to sunlight over time. This property is essential for maintaining the long-term visibility and effectiveness of road markings, thereby ensuring road safety.

Improving Mechanical Properties: Calcium carbonate can enhance the mechanical properties of thermoplastic road marking paints, such as tensile strength and abrasion resistance. This contributes to the durability of the markings, allowing them to withstand traffic wear and environmental stresses over an extended period.

Anti-Skid Properties: In some formulations, calcium carbonate may be modified to impart anti-skid properties to thermoplastic road marking paints. This helps to improve traction and grip for vehicles, particularly in wet or slippery conditions, reducing the risk of accidents and enhancing road safety.

Compatibility: Calcium carbonate is compatible with other ingredients commonly used in thermoplastic road marking paint formulations, such as resins, pigments, and additives. Its fine particle size and uniform distribution facilitate smooth mixing and dispersion within the paint matrix, ensuring consistent performance and appearance.
