Résumé : |
In decorative coatings, the use of pigment concentrates is a modern and flexible way to produce colored paints. Especially in waterborne applications, these concentrates have to be suitable for a broad range of different binder technologies. Because of that, the concentrate formulations are usually free of binders and feature a broad compatibility. Furthermore, the demands in terms of storage stability, color strength and cost efficiency are very high. These demands are addressed directly to the used additive technology. The additive has to induce outstanding viscosity reduction to achieve the highest pigment loads and the most economic grinding. It has to stabilize the pigments over a long period of time without any change in viscosity and it has to develop maximum color strength to avoid any waste of expensive pigments. |
