| Crystalline Calcium Carbonate |

Zetafil CST 2 is based on a very white, pure crystalline CaCO3.
Zetafil CST2 is coated by an organic medium which renders the surface of the inorganic particles to an organic one, thus achieving full compatibility of the filler to an organic media.
Due to its special particle size distribution, Zetafil CST 2 is easily dispersed.
Zetafil CST2's brightness value (95.5) enable formulators to economise in Titanium Dioxide by reducing its percentages in the end product.
