Importance of calcium carbonate
Industrial coatings are primarily used for protection against potentially adverse environmental conditions. They are formulated below the critical pigment volume concentration and with lower filler content than emulsion paints. However, the selection of the appropriate filler is still of great importance because of the potential impact on sheen, viscosity, and durability.
Besides its wide application in primers, Calcium Carbonate has become a suitable component in topcoats, where high gloss and good gloss retention are in demand. Calcium Carbonate can also be used to adjust the gloss level in other applications, such as powder coatings.
