DISPERBYK-2117

Solvent-free wetting and dispersing additive for solvent-borne and solvent-free pigment concentrates and printing inks (medium-polarity to polar). Main use is to disperse carbon blacks and phthalocyanine pigments (blue and green). DISPERBYK-2117 deflocculates pigments and stabilises them by means of steric hindrance. The deflocculating property of the additive results in increased gloss, colour intensity, transparency or hiding power and a reduced mill base viscosity. DISPERBYK-2117 is recommended for use in pigment concentrates and solvent-borne printing inks, particularly for medium-polarity to polar flexographic and gravure printing inks based on alcohol-soluble cellulose nitrates.
