Abstract
A temporary protective coating is provided over a coated glass substrate. The temporary protective coating is preferably applied in solid form (i.e., as opposed to liquid form) so that no significant curing is needed. Moreover, the temporary protective coating can be easily removed by simply peeling it off. In certain example embodiments, the temporary protective coating is applied after heat treatment and is removed by peeling it off before the coated substrate is coupled to another substrate to form a window unit such as an IG window unit or a laminated vehicle windshield.
Claims24
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, adhering a flexible protective sheet in non-liquid form to a top surface the low-E coating, without or without an adhesive layer, to form a protected coated article;
- peeling the protective sheet off of the low-E coating to form an unprotected coated article;
- and
- 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.
A method of making a window unit, the method comprising:
- forming a multi-layer coating on a glass substrate;
- heat treating the glass substrate with the coating thereon;
- after said heat treating, adhering a flexible protective sheet in non-liquid form to a top surface the coating, without or without an adhesive layer, to form a protected coated article;
- peeling the protective sheet off of the coating to form an unprotected coated article;
- and
- after peeling the protective sheet off of the coating, coupling the heat treated coated article including the glass substrate and coating to another substrate to form a window unit.
A method of making a window unit, the method comprising:
- forming a multi-layer coating on a glass substrate;
- heat treating the glass substrate with the coating thereon;
- after said heat treating, adhering a flexible protective film in non-liquid form to a top surface the coating, without or without an adhesive layer, to form a protected coated article;
- peeling the protective film off of the coating to form an unprotected coated article;
- and
- after peeling the protective film off of the coating, coupling the heat treated coated article including the glass substrate and coating to another substrate to form a window unit.
