| Résumé : |
A review of the issues in achieving good rheological behaviour in compliant coatings is presented, particularly with respect to pigment dispersion. Polymeric dispersants have been specifically developed to overcome some of the problems posed by changes in technology and reduce the effect of the dispersed pigment on the rheology of the finished paint or ink. Examples are discussed on multi-compatible solvent tinters, UV systems and high solids coatings. |
| Note de contenu : |
- Structure and function of polymeric dispersants : - The polymer chains sterically stabilise the pigment; - The surface of inorganic pigments is more reactive than the surface of organic pigments
- Benefits of using polymeric dispersants : - A positive impact on the rheology; - Reduced milling time
- Use of polymeric disperants in industrial tinters : - Improved compatibility with base paints; - Improved breadth of polymeric dispersant compatibility
- Reduction of solvent (VOC) in high solids coatings
- Polymeric dispersants reduce the interparticulate attraction between the pigment particules
- UV Inks and Coatings : - Overcome deficiencies using polymeric dispersants |
