Coated Calcium Carbonate

Coated Calcium Carbonate is a refined form of calcium carbonate that is treated with a surface coating, typically stearic acid or other organic compounds. This coating enhances the material’s properties, making it highly desirable for specific industrial applications. The coating improves its dispersibility, hydrophobicity (water repellence), and compatibility with organic polymers, making it particularly useful in industries such as plastics, paints, and rubber.

At Shree Sai Calnates India Pvt. Ltd., coated calcium carbonate is manufactured using advanced techniques to ensure uniform coating and consistent quality. The company focuses on providing a product that optimizes performance in various applications, catering to the growing demand for high-quality, tailored calcium carbonate solutions. Their expertise in the production of both coated and uncoated calcium carbonate allows them to offer the best product for a wide range of industrial needs
