Zetafil CST CA is described on a very white, pure crystalline CaCO3. It is coated by an organic agent which transforms 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 CA is easily dispersed (especially in compounds for cables). Zetafil CST CA’s brightness value enables formulators to economize in Titanium Dioxide by reducing its percentages in the end product.
