Abstract
Hydrophilic, self-cleaning coating compositions and methods to make and use the compositions are disclosed. The coatings comprise perlite and/or expanded perlite that are activated with hydrophilic agents. The perlites when incorporated in paints provide hydrophilic, self-cleaning and/or biocidal property to the coating.
