Product overview
Coated and uncoated calcium carbonate powders differ primarily in their surface treatment and properties. Uncoated calcium carbonate powder, derived from natural limestone or marble, consists of pure calcium carbonate with minimal processing. It is used widely as a filler and pigment in various industries, including plastics, paints, and paper, where it improves mechanical properties and opacity. In contrast, coated calcium carbonate powder undergoes additional surface treatment with fatty acids (e.g., stearic acid) or other chemicals to modify its surface properties. This coating enhances dispersibility, improves compatibility with polymers, and provides better moisture resistance. Coated calcium carbonate is preferred in applications requiring improved rheological properties, higher gloss, and reduced abrasiveness. It finds extensive use in industries such as adhesives, sealants, and rubber manufacturing, where these enhanced characteristics are critical for achieving desired performance and product quality. Both types of calcium carbonate powders offer versatile solutions tailored to specific industrial and commercial requirements.
