High-Quality Precipitated Calcium Carbonate (PCC) for Coatings and Paints - China Suppliers & Factory
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.

Frequently Asked Questions
QWhat is precipitated calcium carbonate (PCC) used for in coatings and paints?
Precipitated calcium carbonate is used in coatings and paints as a functional filler to improve storage stability, enhance flowability and workability, increase coating thickness and hardness, and improve scratch and wear resistance. It also contributes to a more uniform application during spraying or roller coating processes.
QHow does precipitated calcium carbonate improve coating storage stability?
The addition of precipitated calcium carbonate helps prevent stratification or sedimentation in coatings after prolonged storage. It stabilizes the suspension of pigments and other components within the coating formulation, ensuring consistent quality and performance over time.
QWhat is the typical purity level of your precipitated calcium carbonate for coatings?
Our precipitated calcium carbonate for coatings has a CaCO₃ content of ≥95%, with a brightness of ≥95% and an activation rate of ≥98%. The average particle size ranges from 0.5 to 4 μm, making it highly suitable for fine coating applications.
QIs your precipitated calcium carbonate suitable for exterior wall coatings and floor coatings?
Yes. Our precipitated calcium carbonate is particularly well-suited for high-durability applications such as exterior wall coatings and floor coatings. It increases the hardness and wear resistance of coatings, allowing them to perform reliably in high-wear environments and extending their overall service life.
QDo you offer OEM or custom specification services for precipitated calcium carbonate?
Yes, we offer comprehensive OEM services. Our professional R&D team can flexibly customize product specifications, particle size, packaging, and other parameters based on your specific application requirements, helping you achieve cost optimization without paying for unnecessary features.
QWhat quality assurance measures are in place for your precipitated calcium carbonate products?
We maintain our own large-scale mining resources and select top-grade raw materials from the source. Quality is strictly controlled throughout the entire production process. Each batch meets defined specifications for purity, particle size, oil absorption, pH, brightness, and moisture content, ensuring consistent product quality and stability for every order.
