<p>The invention provides a substrate (e.g., a glass pane) having generally opposed first and second major surfaces. At least one of these major surfaces bears a functional coating and has a peripheral region that is substantially free of the funcitonal coating. Another embodiment provides a multiple-pane insulating galss unit comprising two spaced-apart panes and a spacer joining confronting, inner peripheral surfaces of the panes. At least on of the panes has a coated outer surface. the coated outer surface has a peripheral region that is substantially free of the coating. The invention also provides methods for treating a coated substrate that has generally opposed first and second major surfaces each bearing a functional coating. The coating is substantially removed from a peripheral region of the first major surface. Likewise, the coating is substantially removed from a peripheral region of the secon major surface. A further embodiment provides a barrier layer that prevents cotact between glazing compound and an exterior coating. Durable compounds are provided in yet another embodiment.</p> |
