Abstract
This invention relates to coating glass beads with a mixture of substances which mixture comprises a first substance which if used alone would tend to make the beads hydrophobic while leaving them oleophilic and as second substance which if used alone would tend to make the beads both hydrophobic and oleophobic. Said coated beads maybe used in a synthetic polymeric matrix, as a coating over paint and as a coating on a road surface.
