Solubility parameters, hydrophilicity, hydrophobicity, acidity, and basicity of pigments, resins, and solvents were evaluated, and these values were used to apply affinity concepts to pigment dispereion.
The results of these studies show that careful adjustment of the interactions or affinities among pigments, resins, and solvents is essential in designing the ideal pigment dispersions for organic coatings, and some important factors for the adjustment of the interactions, shown above were found.
