UNICARB NRS5000 is Precipitated Calcium Carbonate Ultra-Fine Powder with good dispersion properties, manufactured from a high purity raw material, is used and appreciated in the paint manufacturing industry due to its pigment dispersion features, thus to reduce dosages and cost in finished formulations. In paint, precipitated calcium carbonate, is the main pigment extender used to reduce the Titanium Dioxide (TiO2) dosages, which is higher in cost, and also to provide opacity and brightness.
Titanium dioxide (TiO2) due to its high refractive index, is widely used in the paint industry as a white pigment. In order to reduce this high cost of TiO2, a part of TiO2 is generally substituted by some other industrial mineral fillers; however, this substitution affects the quality of paints in terms of stability, coverage (opacity), brightness (gloss), scrub resistance (film toughness), etc. The quality of paints produced by PCC along with its rheological properties was evaluated based on standard features in both wet and dry paints such as viscosity, density, opacity and gloss values.
