Zetafil CST 1 |
|
Pure Crystalline Calcium Carbonate |
|
Zetafil CST1 is based on a very white, pure crystalline CaCO3. Zetafil CST1 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 CST1 is easily dispersed. Zetafil CST1's brightness value (96.5) enable formulators to economise in Titanium Dioxide by reducing its percentages in the end product. *Plastics: - Rigid PVC: Window profiles, Calendered Sheets, Profiles / pipes, Mouldings - Polyolefins: Color Master batch, Compound / Master batch for mouldings *Paints: High gloss enamesl |
