| Résumé : |
Surface chemistry is dedicated to processes and phenomena on interfaces, whereas colloid chemistry is focused on properties and behavior of dispersions.
This series of articles is to describe colloid basics of paint and coating technology, where disperse systems are widely used (latex and emulsion-type binders and paints, pigment grinds and pastes, hydro- and organosols, powder paints, etc.) and surface phenomena play important (sometimes decisive) roles in a dozen of technology processes as well as in the formation of coating structures, thereby influencing coating properties. Unfortunately, with the exclusion of particle sizing, colloid methods are still not sufficiently exploited in paint technology, although their effectiveness in R&D, for optimization of coating compositions and for trouble-shooting in paint production and application is commonly recognized.
The series will provide paint specialists with useful colloid concepts, mechanisms, formulae, methodics and examples for better understanding and controlling of various steps of paint manufacturing and application. |
