High-Quality Precipitated Calcium Carbonate (PCC) from China Suppliers & Factory for Coating and Painting Applications
Product Description
Improving the storage stability of coatings and enhance their flow properties and workability.
The addition of precipitated calcium carbonate can improve the stability of the coating, preventing stratification or sedimentation after prolonged storage. Precipitated calcium carbonate improves the flowability and workability of the coating, resulting in a more uniform application during the coating process and reducing dripping, sagging, or splashing. It enhances the application performance of the paint, making it easier to handle, especially in applications such as spraying or roller coating.
Increasing the thickness and hardness of coatings, enhancing their scratch and wear resistance.
Precipitated calcium carbonate can increase the thickness and hardness of coatings, improving their scratch resistance and wear resistance. This makes the coatings perform better in high-wear environments and extends their service life, making them particularly suitable for applications requiring high durability, such as floor coatings and exterior wall coatings.
