Abstract:
1. A method of glass edge coating, comprising: providing a glass article having opposing surfaces separated by a thickness of glass and bounded by a perimeter edge; arranging a nozzle of a jetting dispenser in opposing relation to the perimeter edge of the glass article with a select standoff distance between the nozzle and the perimeter edge; supplying a coating material to the jetting dispenser; jetting a plurality of droplets from the nozzle of the jetting dispenser, wherein the droplets drop on the perimeter edge after falling through the standoff distance to form beads of coating material on the perimeter edge, whereafter each bead flows in a plurality of directions on the perimeter edge to form a coating on the perimeter edge that is substantially limited to the perimeter edge; effecting a relative motion between the nozzle and the perimeter edge during the jetting such that the beads are deposited at a plurality of locations along the perimeter edge; and maintaining a viscosity of the coating material in the jetting dispenser in a range from 500 to 10,000 cp during the jetting.
