    • 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.
    • 本发明提供了具有大致相对的第一和第二主表面的基底(例如,玻璃窗)。 这些主表面中的至少一个具有功能性涂层,并且具有基本上没有功能涂层的周边区域。 另一实施例提供了一种多窗格绝缘板,其包括两个间隔开的窗格和连接窗格的相对的内周表面的间隔件。 至少在窗格上有一个涂层的外表面。 涂覆的外表面具有基本上没有涂层的周边区域。 本发明还提供了一种用于处理涂覆的基材的方法,该基材具有大致相对的第一和第二主表面,每个主表面均具有功能性涂层。 涂层基本上从第一主表面的周边区域去除。 同样地,涂层基本上从第二主表面的周边区域除去。 另一实施例提供了防止玻璃化合物和外部涂层之间的共同作用的阻挡层。 在另一个实施方案中提供耐久化合物。
