| Résumé : |
The inorganic treatment of commercially available titanium dioxide pigments determines to a large extent which type of wetting and dispersing additive will work best for that individual pigment type. For basic surface treatments, anionic and electroneutral additives provide the best deflocculation. For neutral surface treatments, electroneutral additives are best, while cationic additives work best with acidic SiO2- treated pigments. The isoelectric point of each pigment can be used to select the best additive. Wetting and dispersing additives provide not only a high level of pigment stabilization, but may also significantly improve the chalking resistance and durability of high-gloss topcoats. |
