Abstract
A glass article includes a glass substrate and a coating disposed on the glass substrate. The coating includes a glass frit material and a binder material. The binder material includes a first polymer that has cross-linked first polymer chains and a second polymer that has second polymer chains that are linear, branched, or cross-linked. The cross-linked first polymer chains and the second polymer chains form an interpenetrating network in which the second polymer chains are intertwined on a molecular scale with the cross-linked first polymer chains.

A glass article comprising:
- a glass substrate;
- a coating disposed on the glass substrate, the coating including a glass frit material and a binder material, the binder material comprising a first polymer having cross-linked first polymer chains and a second polymer having second polymer chains that are linear, branched, or cross-linked, and the cross-linked first polymer chains and the second polymer chains forming an interpenetrating network in which the second polymer chains are intertwined with the cross-linked first polymer chains and further wherein the coating includes less than 11% of the binder material relative to a total weight of the coating;
- and
- wherein the coating is chemically bonded to the glass substrate.
