Abstract
Paints are mainly consists of pigmens, resins and solvents. As for the design of paint formulations, especially of mill base formulations, it is important to consider how to stabilize the dispersed states of pigment. In the practical paint systems including both of solvent and water borne paints, steric stabilization by resin adsorption on the pigment surfce is necessary.
The driving forces of resin adsorption in solvent and water borne paints are acid-base and hydrophobic interactions, respectively. Pigments and resins must be chosen in mill base formulaions so thatt hose strong interaction take place. Characterizing methods of acid/base and hydrophilic/hydrophobic properties of pigments and resins are briefly reviewed. The chracteristics of pigments and resins are correlated with the pigment dispersibility.
