China PCC (Precipitated Calcium Carbonate) Suppliers & Factory for Coatings, Painting, and Industrial 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.

Frequently Asked Questions
Q
What is precipitated calcium carbonate (PCC) used for in coatings and paints?
Precipitated calcium carbonate (PCC) is used in coatings and paints as a functional filler to improve storage stability, enhance flowability, increase coating thickness and hardness, and improve scratch and wear resistance. It also helps achieve a more uniform application during the coating process.
Q
How does precipitated calcium carbonate improve the storage stability of coatings?
PCC prevents stratification or sedimentation in coatings after prolonged storage. Its fine particle size and high activation rate allow it to remain evenly dispersed within the coating formulation, maintaining consistent product quality over time.
Q
What is the typical particle size and purity of this precipitated calcium carbonate?
The average particle size ranges from 0.5 to 4 μm, with a CaCO₃ purity of ≥95% and a brightness of ≥95%. The activation rate is ≥98%, ensuring excellent compatibility and performance in coating applications.
Q
Is OEM or custom specification service available for this product?
Yes. OEM services are available, allowing customers to flexibly customize product specifications, particle size, packaging, and other parameters to meet specific application requirements while optimizing overall costs.
Q
Is this precipitated calcium carbonate environmentally friendly?
Yes. The product is sourced from an independent green mine raw material production base, forming an eco-friendly industrial chain that integrates environmentally responsible mining with advanced nano material deep processing technology.
Q
What types of coatings are most suitable for using this precipitated calcium carbonate?
This precipitated calcium carbonate is particularly suitable for high-durability applications such as floor coatings and exterior wall coatings. It is also effective in spray-applied and roller-applied paints where uniform flow, hardness, and long-term wear resistance are critical requirements.
