Patent ID: 7125462

Claim:
A method of making a vehicle windshield, the method comprising: providing a glass substrate; silk-screen printing a water soluble ceramic paste mask onto at least one select area of the glass substrate in liquid and/or slurry form, the water soluble ceramic paste mask comprising an organic portion and a ceramic portion wherein an organic:ceramic ratio of the respective portions by weight is from about 3:1 to 1:1 when the ceramic paste mask is initially silk-screen printed onto the substrate, wherein the organic portion comprises a synthetic resin and propylenoxyd; drying the water soluble ceramic paste mask when the mask is on the glass substrate; after drying the water soluble ceramic paste mask on the glass substrate, sputtering a multi-layer low-E coating onto the substrate so that the low-E coating is provided over the mask in the at least one select area where the mask is provided and directly on the substrate in an area where the mask is not provided; removing the mask and a portion of the low-E coating provided thereon from the select area of the substrate, but not from the area of the substrate where the mask was not provided, using at least water at a temperature of no greater than 60 degrees C. thereby forming a partially coated substrate; and laminating the partially coated substrate to another substrate in forming the vehicle windshield.
