Zetafil CST 1 is described on a very white and pure crystalline CaCO3 raw material. Zetafil CST 1 is specially coated by an organic agent which transforms the surface of the inorganic particles into an organic one, thus achieving full compatibility of the filler to the resin. Due to its special particle size distribution and hydrophobic surface, Zetafil CST 1 is easily dispersed. Zetafil CST 1’s brightness value enables formulators to economize in Titanium Dioxide. The abrasive index of Zetafil cst 1 is exceptionally low due to the purity of the raw material, the fineness of its particles and the coating of its surface.
