Strengthened glass substrates with glass frits and methods for making the same

An automotive glazing comprising:

• a glass substrate comprising a first surface, a second surface opposite the first surface, a perimeter edge, and any one or more of an electrical lead, wires, and antennas, the glass substrate further comprising a compressive stress layer extending from a surface of the glass substrate into a thickness of the glass substrate, the compressive stress layer having a depth of layer DOL and a fired compressive stress CSf that is greater than or equal to 420 MPa and a substrate coefficient of thermal expansion CTES is in a range from about 80×10−7/° C. to about 95×10−7/° C. over a temperature range from 0° C. to 300° C.;
• a glass frit fully vitrified and bonded to at least a portion of the first surface of the glass substrate directly adjacent to the perimeter edge of the glass substrate, wherein the glass frit has a softening point of less than or equal to 400° C., a glass transition temperature which is less than or equal to 375° C., a sintering temperature of less than 450° C., and a frit coefficient of thermal expansion CTEF which is within +/−10×10−7/° C. of the substrate coefficient of thermal expansion CTES.
