Abstract
A method of making a laminated glazing unit having an interfacial coating on a laminated ply includes depositing the coating on the laminted ply and then removing a peripheral portion of the coating. Specifically, the peripheral portion of the coating is exposed to a laser beam of sufficient power to remove the coating. The exposure time and power level are controlled to avoid damage to the underlying substrate. Subsequently, the coated substrate ply is laminated to a ply of PVB or other flexible polymeric laminating material. A substantially direct laminating bond is formed between the laminating ply and the surface of the substrate ply in the peripheral area from which the coating has been removed. The peripheral seal thus formed is environmentally durable and protects the interior of the interface from degradation due to progressive edge corrosion and the like.
