VOK®- Disper 2205 is characterized by good dispersion stability for inorganic and organic pigments in solvent based and solvent-free paint systems. Use VOK ®- Disper 2205 disperse pigment can reduce thixotropy and produce Newtonian flow behavior. It can also improve color intensity and transparency, and improve luster and reduce fog shadow. In addition, due to its good viscosity reduction effect, VOK®- Disper 2205 can increase the addition amount of organic and inorganic pigments in pigment concentrate slurry. This product is suitable for color separation grinding and co grinding. VOK®- Disper 2205 is also suitable for acid curing systems.
