One of the most important steps in the production of pigmented coatings is the<br />
homogeneous distribution of solid pigments within the liquid binder solution. If this<br />
pigment grinding step is not optimized, a wide variety of defects can occur:<br />
Flocculation (/en/wetting-and-dispersing/deflocculating-wetting-and-dispersingadditives/)<br />
Gloss reduction<br />
Color shift<br />
Separation, (/en/wetting-and-dispersing/prevention-of-floating/)<br />
formation of Bénard cells (/en/wetting-and-dispersing/prevention-of-floating/)<br />
Settling.<br />
Properties related to the flow characteristics of the coating system, such as<br />
Sagging<br />
Leveling<br />
can also be negatively affected.<br />
