Vanconol® LFS-209 Wetting Dispersant for Waterborne Systems
Vanconol® LFS-209 High-Efficiency Wetting and Dispersing Agent for Waterborne Systems
Abstract
Vanconol® LFS-209 is a high-efficiency wetting and dispersing agent developed to address pigment dispersion challenges in waterborne coatings, printing inks and adhesives. Its chemical composition is a modified polymeric polyether phosphate ester salt and surfactant solution. Its key benefits include significantly reducing grinding system viscosity, improving pigment dispersion efficiency and being particularly suitable for preparing highly concentrated inorganic pigment slurries. Compared with conventional solutions, it provides a pronounced viscosity-reducing effect on inorganic pigment colorants, is APEO-free, and is a suitable option for preparing waterborne pigment dispersion slurries.
