Wetting dispersant for solvent-based, solvent-free coatings and printing inks, stabilizing inorganic pigments, especially titanium dioxide. The abrasive viscosity can be significantly reduced. The additive deflocculates the pigment through steric hindrance. Due to the small particle size of the deflocculated pigment, it can obtain a high gloss and improve the color intensity. In addition, increased transparency and hiding power. The additives on pigments, especially titanium dioxide. Because of its anionic properties, the dispersant is ideal for acid-catalyzed systems such as coil coatings.
