DOLOMITE
DOLOMITE
Dolomite is double carbonate of calcium and magnesium. Chemical formula of dolomite is clusters of CaMg(CO3)2 Extremely Pure and White dolomite deposits are found in Turkey, where name “marble” took it “original name during history from Anatolia. Homogenous Cyrstalline structure with high natural whiteness are all main parameters of Prima Dolomite grades.
Dolomite is harder and more dense than Calcium Carbonate, and slightly more acid resistant than Calcium Carbonate.

- ABS, SAN and other thermoplastics.
- Water based paints
- Plasters
- Matt wall paints
- Concrete and gloss paints
- Undercoats and rustproofing primers
- Coil coatings
- Road marking paints
- Adhesives, silicone and sealing compounds
