A high-performance, polymeric surface active agent designed for the optimal stabilization of a wide range of particle and pigment chemistries in aqueous systems. Based on a unique blend of moderate molecular weight (10-25 kDa) polymeric chemistries, ZetaSperse 3400 dispersant can provide strong electrosteric stabilization through a synergistic combination of ammonium-neutralized carboxylic acid anions and sterically-stabilizing polyether combs. Aliphatic, aromatic, and ester moieties offer diverse interactions for a variety of particle and pigment chemistries, providing strong surface affinities and shock resistance. A lower molecular weight dynamic stabilizing component can provide excellent wetting, excellent milling efficiency, and optimal performance throughout the dispersion process.
