| Résumé : |
Various types of ionic and non-ionic dispersants have been classified by their ability to stabilise titanium dioxide pigment suspensions in water. It was found that some non-ionic dispersants produced suspensions that exhibited full steric stabilisation as opposed to electrosteric stabilisation that occurs with ionic dispersants. A high level of steric stabilisation was found to relate to greater flocculation resistance in both the wet and dry phases, which can result in improved paint stability and higher opacity. |
