The paper considers the impact of various dispersants on the dispersion time of pigment paste for cathodic electrodeposition primer and on some properties of the formed coating. The authors demonstrate that a dispersant based on nonionic surfactants (tetramethyldecynediol) in ethylene glycol enables dispersion of pigments and fillers in aqueous medium to the required particle fineness of ~15 μm (by grindometer) in minimal time. When using this dispersant, the best coating properties are observed.
