Synopsis

Opacity is the result of a rather complex interplay of various components and parameters. In practice, this can be easily achieved by adding white pigment such as titanium dioxide. The required amount of white pigment for high opacity (sometimes referred to as coverage or hiding efficiency) depends on the binder content, or more precisely on the so-called pigment volume concentration (PVC).

However, if we add real-world economic considerations, the formulation might change significantly.

Mineral fillers based on Calcium Carbonates can reduce formulation cost sharply. Furthermore, new developments in all major product groups, i.e. ground calcium carbonate (GCC), precipitated calcium carbonate (PCC) and modified calcium carbonate (MCC), offer new opportunities to optimize the performance of paints & coatings as well as the ecological footprint of the formulation.

This presentation provides examples of how ultrafine ground calcium carbonate (UFGCC), specific colloidal PCC and specially designed MCC materials help to optimize decorative emulsion paint formulations and contribute to the opacity boosting of paints. The enhancement of titanium dioxide efficiency is a key element of the formulation optimization.
