Zetafil cst 3

CAS Number
471-34-1
EC Number
207-439-9
Chemical Name
Calcium Carbonate

Zetafil CST 3 is described on a very white, pure crystalline CaCO3. Zetafil CST 3 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 CST3 is easily dispersed and can increase the % of fillers in the compound and coatings. Zetafil cst 3’s high brightness value assists the reduction of TiO2 in white compounds or coatings.
