Читать книгу Additives for Waterborne Coatings - et al. - Страница 28

During production of water-borne emulsion paints, extenders such as calcium carbonate and titanium dioxide are used as a mill base. Grinding these materials is not particularly demanding and, because of their excellent viscosity reduction, polyacrylate salts are widely used. Electrostatic repulsion is sufficient in this case and the cost-performance ratio of these additives is appropriate to the application.
