Paints, Coatings & Inks

Omya offers an extensive range of standard and specialty grades of calcium carbonate with different particle sizes and optical values. The filler selection can significantly influence the paint properties. The 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, but should be considered as a functional filler rather than an extender due to its ability to enhance paint performance. Ultrafine ground calcium carbonate types and modified calcium carbonates provide special properties in decorative coatings which allow the usage of titanium dioxide to be optimized.

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.
