About Precipitated Calcium Carbonate

High Purity lime stone is calcined in Lime Kiln to produce quick lime which is slaked and further carbonated to produce PCC slurry, which is filtered and dried to produce pure white PCC Powder.

In paints, PCC is used as an anti-setting agent and in emulsion paints as a white opacity agent. In Printing Ink used as an extender to control strength and body of the ink. As a polishing agents in window and mirror cleaners.

PCC is used for paper coating, and as a filler in paper. It imparts better opacity, gloss, high brightness, surface finishing and improves printability.

Most importantly, it reduces the amount of wood fiber required to make paper, subsequently reducing the number of trees needed.

Also used as a filler in Leather Cloth, Wallpaper, Footwear, Shoes Compounding etc.
