VP 6071 Waterborne polymer dispersant

6071 Waterborne Polymer Dispersant is a high-performance additive engineered to optimize the stabilization of inorganic pigments, organic pigments, and carbon blacks within aqueous systems. Utilizing advanced controlled polymerization technology, this dispersant features a high molecular weight backbone equipped with specialized pigment-affinic groups. These functional moieties anchor firmly to the pigment surface, while the solvated polymeric chains extend into the aqueous medium, providing robust steric hindrance and electrostatic repulsion. This dual stabilization mechanism prevents flocculation, reduces mill-base viscosity, and significantly improves the dispersion efficiency during the grinding process. 6071 is specifically formulated to meet the rigorous demands of modern industrial coatings and high-end inkjet inks, where color development and long-term stability are paramount. Its non-ionic/anionic nature ensures broad compatibility with various resins, including acrylic, polyurethane, and epoxy emulsions. By minimizing particle size distribution and enhancing interfacial tension reduction, 6071 ensures superior gloss, transparency, and flocculation resistance in diverse water-based formulations.
