Colloidal / Light Calcium Carbonate

Large-particle colloidal and light (precipitated) calcium carbonates are used in applications that emphasize specific functional performance or filling ability. As anti-blocking agents in films, they provide excellent slip properties, while as fillers in sealants, they contribute to viscosity adjustment and improved cost performance. Their larger particle size allows workability to be maintained even at high loading levels and enables optimization of product properties.

Small-particle colloidal and light calcium carbonate, with its fine particle size, improves the surface smoothness and gloss of paints and sealants. It also contributes to the production of thinner films, balancing aesthetics and functionality. In recent years, it has become an important filler that maximizes material performance in fields demanding higher quality and precise finishing, such as high-resolution displays, optical lenses, and high-performance automotive paints.
