Laser ablation / scribing techniques and / or related methods for coating the insulating glass unit before and after assembly

摘要

Certain exemplary embodiments of the invention are glass or other groups of pre- or post-laminated assemblies, pre- and post-assembled insulating glass units, and / or other products to delay or prevent coating corrosion. It relates to a technique for laser ablation / scribing the peripheral edge of a coating on a material (eg, low emissivity, mirror, or other coating). For example, using a laser of 1064 nm or other wavelengths, metals and / or other low emissivity or other coatings of already laminated or already assembled insulating glass units or other products, eg, on their outer edges. Wires can be scribed into the metal layer. Scribbled lines slow down, or even prevent, the occurrence of electrochemical corrosion by reducing electron mobility from the center of the coating to the environment. Products, methods, and kits related thereto are also contemplated herein.
