Abstract
A concentrated nanocomposite dispersion which includes a silicate filler and a matrix polymer dispersed in an aqueous medium. The dispersions are condensed by selectively removing liquid therefrom, to provide high solids coating formulations. The concentrated formulations provide coatings which are good barriers to oxygen and other gases.
