High-Quality Precipitated Calcium Carbonate 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
Q
What is precipitated calcium carbonate (PCC) and how is it used in coatings?
Precipitated calcium carbonate (PCC) is a synthetically produced form of calcium carbonate with a controlled particle size and high purity. In coatings and paints, it is used as a functional filler to improve storage stability, flow properties, hardness, scratch resistance, and overall application performance.
Q
How does precipitated calcium carbonate improve coating stability?
PCC helps prevent stratification or sedimentation in coatings during prolonged storage. Its fine particle structure distributes evenly throughout the formulation, maintaining a consistent texture and preventing the coating from separating into layers over time.
Q
What is the typical particle size range of this PCC product for coatings?
The average particle size of this precipitated calcium carbonate product is between 0.5 and 4 μm, which is optimized for use in coatings and paints to ensure smooth application, uniform dispersion, and excellent surface finish.
Q
Is OEM customization available for this product?
Yes, OEM services are available. Product specifications, particle size, packaging formats, and labeling can be flexibly customized to meet specific customer requirements, enabling cost-effective solutions tailored to your application needs.
Q
Is this precipitated calcium carbonate environmentally friendly?
Yes. The raw materials are sourced from an independent green mine production base, and the entire production process is designed to support an environmentally friendly industrial chain. The product is non-toxic, safe to handle, and compliant with environmental standards for coating applications.
Q
What types of coatings are most suitable for this PCC product?
This precipitated calcium carbonate is particularly suitable for high-durability coating applications such as floor coatings, exterior wall coatings, industrial protective coatings, and architectural paints. Its high brightness (≥95%), controlled pH (8.0–10.0), and low moisture content (≤0.4%) make it compatible with a wide range of coating systems.
