Industrial Coatings & Inks
Industrial coatings are primarily used for protection against potentially adverse environmental conditions. The focus in these applications is on durability; optical properties are often less important.
Industrial coatings are formulated below the critical pigment volume concentration and with lower filler content than emulsion paints. However, the selection of an appropriate filler should not be neglected because of the potential impact on gloss, viscosity and durability.
| Application | Calcium Carbonate Content |
| Powder coatings | 5 - 20% |
| Industrial coatings | 5 - 20% |
| Road marking paints | 30 - 50% |
| Primer | 5 - 20% |
| Inks | up to 15% |
Natural calcium carbonate has an alkaline pH-value and low oil absorption. This important combination of properties is ideal for primers and primer surfacers.
Calcium carbonate has become an appropriate component for top coats, where high gloss and good gloss retention are demanded. In other applications, such as powder coatings, calcium carbonate is employed to adjust gloss level.
The wide variety of applications calls for fillers with a wide range of different characteristics. The natural properties of calcium carbonate, combined with Omya’s application expertise, ensure the right product for every application.
