METHOD OF MODIFYING THE WETTABILITY OF GLASS BEADS,GLASS BEADS,POLYMERIC MATERIAL INCORPORATING SUCH GLASS BEADS,AND METHOD OF APPLYING REFLECTIVE MARKINGS TO A SURFACE

摘要

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.
