Abstract:
1. A method of making an insulating glass (IG) window unit, the method comprising: sputtering a multi-layered low-E coating onto a glass substrate, wherein the low-E coating comprises at least one infrared (IR) reflecting layer comprising silver sandwiched between at least first and second dielectric layers; thermally tempering the glass substrate with the low-E coating thereon; after said tempering, applying a thermoplastic composition in liquid form to a top surface of the low-E coating, wherein the thermoplastic composition consists essentially of a hot melt adhesive, and one or more of a metallic salt of a fatty acid, a foaming agent, a surfactant, an inert gas and resin, and cooling the thermoplastic composition to form a protective sheet so as to create a protected coated article; peeling the protective sheet off of the low-E coating to form an unprotected coated article; after peeling the protective sheet off of the low-E coating, coupling the tempered coated article including the glass substrate and low-E coating to another substrate to form an IG window unit; and wherein the thermoplastic composition comprises a foaming agent.
