A high degree of whiteness weather resistance, inertness, low abrasiveness, a high hiding power and a pH stabilizing effect are among its decisive advantages.

Binder concentration can be regulated via particle shape and packing density, while opacity depends on particle fineness and particle size distribution. Hydrophobic calcites also improve the corrosion-inhibition and rheological properties of coating systems.

A focal point in application technology research is the development of a new generation of extremely fine nature calcites which do not reagglomerate. Their primary particle diameter lies close to the theoretical maximum, so that the optimized fillers can replace expensive white pigments.

Coating systems with high packing densities are involved in another development thrust. Here, shorter curing times are achieved due to the capability effect. This is particularly important in water based paints.
