ABSTRACT:
A method of increasing the hydrophobicity of solid materials. The inventive method comprises the steps of: (a) metal ion activating the surface of a solid substrate material to provide reactive metal sites on the surface and (b) chemically bonding a surfactant to the surface at the reactive metal sites. Titanium dioxide pigments and other particulate property modifiers treated in accordance with the inventive method are more readily dispersed in polymer compositions.
