Coated calcium carbonate refers to a form of calcium carbonate in which the individual particles of the mineral are coated or encapsulated with a layer of a different material. This layer can be composed of various substances, such as stearic acid, fatty acids, or other polymers. The purpose of the coating is to modify the surface properties of the calcium carbonate particles, such as their hydrophobicity or compatibility with other materials, making them more suitable for specific applications. Coated calcium carbonate is widely used in industries such as plastics, paper, paints, and coatings, where it can improve the properties of the final product, such as brightness, whiteness, and durability.


Coated calcium carbonate has many uses in various industries due to its unique properties. Some of the major uses of coated calcium carbonate include:

  1. Plastics: Coated calcium carbonate is used as a filler in plastics to improve their strength, stiffness, and impact resistance. It also enhances the whiteness and opacity of plastic products, making them more visually appealing.
  2. Paper: Coated calcium carbonate is used as a filler in paper and board products to increase their brightness, opacity, and smoothness. It also improves the printability and ink retention of paper products.
  3. Paints and coatings: Coated calcium carbonate is used as a pigment and filler in paints and coatings to improve their hiding power, gloss, and durability. It also enhances the viscosity and stability of paint formulations.
  4. Adhesives and sealants: Coated calcium carbonate is used as a filler in adhesives and sealants to improve their strength and durability. It also enhances their rheology and thixotropy.
  5. Pharmaceuticals: Coated calcium carbonate is used as an excipient in pharmaceuticals to improve their flowability, compressibility, and stability. It also acts as a buffering agent and antacid.

Overall, coated calcium carbonate is a versatile material that has a wide range of applications in various industries. Its unique properties make it an essential ingredient in many products that we use every day.
