Résumé : |
The physical properties of coatings formulations in the liquid state and the solid state directly arise from interactions which exist between the various components of the formulations. In such systems we can envisage, for the liquid state, the solvent, the resin precursor, the film former, the pigment(s), extenders and any/all additives. In the solid state the solvent is removed. The interplay between the remaining species changes. The solvent provides the basis for mobility, opportunities for change and the possibility of closer approaches to homogeneity within the system (or, in certain instances, greater heterogeneity within the system). |
