  Calcium Carbonate CC-B HOTEN SUPER FINE CC is type of ultra-fine calcium carbonate grains of D50 less than 1.0um made from refined and highly pure limestone by up-to-date power grinding technology and after-treatments. The addition of different after-treatment agents in varied HOTEN SUPER FINE CC models result in different final products of different gloss. As composed of fine and pure white calcium carbonate, most HOTEN SUPER FINE CC products are used in the product formulas having no requirements for weathering resistance.
