Calcium Carbonate for Paint Industry
Precipitated Calcium Carbonate ( PCC ) is an innovative product derived from lime stone, which has many industrial applications. PCC is made by hydrating high- calcium quick lime and then reacting the resulting lime slurry with carbon dioxide. The resulting product is extremely white and typical has a uniform narrow particle size distribution. PCC is available in numerous crystal morphologies and sizes, which can be tailored to optimize performance in a specified application.
Precipitated Calcium Carbonate is used as extender and Opacifying Agent in Paint Industry such as Emulsion, Paint & Polishing Agents for Titanium Oxide which imparts Brightness. It has Aragonite and Calcite structure with different particle size distribution and apparent densities.
