Calcium carbonate for protective coatings

More than fillers, Omya offers an extensive range of standard and specialty grades of Calcium Carbonate with different particle sizes and optical values. Filler selection can significantly influence paint properties. With systematic filler selection, sheen, opacity, and wet-scrub resistance can all be modified to improve the properties of the end product.

 

Calcium Carbonate has established itself as the main extender in paints and coatings. Still, it should be considered a functional filler rather than an extender due to its ability to enhance paint performance. Ultrafine Ground Calcium Carbonate products and Modified Calcium Carbonates provide special properties in decorative coatings that allow titanium dioxide usage to be optimized.

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.
