VOK?- Disper 2117 deflocculates and stabilizes pigments through steric hindrance. The deflocculating property of the additive improves the luster, color strength, transparency or coverage, and reduces the viscosity of the abrasive. VOK?- Disper 2117 is suitable for pigment concentrate and solvent based printing inks, especially for flexographic and intaglio printing inks of alcohol soluble nitrocellulose type with medium polarity to polarity. It is mainly used to disperse carbon black and phthalocyanine pigments (phthalocyanine blue and phthalocyanine green).
