DISPERBYK® 2118 is a solvent-free wetting and dispersing additive for solventborne and solvent-free pigment concentrates, as well as printing inks. It is particularly effective for dispersing carbon blacks and phthalocyanine pigments, making it ideal for flexography, gravure, and solventborne inks. This additive reduces viscosity and functions as both a wetting agent and dispersant, enhancing dispersion and stability in ink formulations. DISPERBYK® 2118 is suitable for high-solids coatings and a variety of ink applications, offering improved performance in both solventborne and solvent-free systems.

Key Features
  • DISPERBYK-2118 deflocculates pigments and stabilizes them by means of steric hindrance.
  • The deflocculating property of the additive results in increased gloss, color intensity, transparency or hiding power, and a reduced mill base viscosity.
  • DISPERBYK-2118 is recommended for use in pigment concentrates and solvent-borne printing inks, particularly for medium-polarity to non-polar flexographic and gravure printing inks based on alcohol-soluble cellulose nitrates.
  • Main use is to disperse carbon blacks and phthalocyanine pigments (blue and green).

Processing Instructions
  • Wetting and dispersion additives should generally be added to the millbase.
  • Only in this way can they be fully effective. In the case of binder-free grinds, the solvent components of the millbase are pre-mixed with the additive whilst stirring and before the pigment is added.
  • If the grinds contain binder, the binder, solvent and additive should be homogenized prior to adding the pigment.
