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.
Claims21
A method of regulating the wettability of glass beads, comprising:
- 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 a second substance which if used alone would tend to make the beads both hydrophobic and oleophobic;
- said first and second substances being present in a proportion effective to attain a desired degree of wettability or bonding to a medium with which said coated beads are to be admixed.
