Polymer edge-covered glass articles and methods for making and using same

摘要

Described herein are various polymer-covered glass and glass-ceramic articles that exhibit improved adhesion between the polymer and the glass or glass-ceramic, along with methods for their manufacture and use. The improved articles generally include a glass or glass-ceramic substrate, a surface-roughened coating disposed on at least a portion of an edge of the glass or glass-ceramic substrate, and a polymer covering disposed on at least a portion of the surface-roughened coating. The surface-roughened coatings beneficially allow the polymer coverings to adhere better to the edge surfaces of the glass or glass-ceramic substrates relative to similar or identical articles that lack the surface-roughened coating.

主权项

1. A polymer-covered article, comprising:
a glass or glass-ceramic substrate; a surface roughened coating having first and second surfaces, wherein the first surface is disposed on at least a portion of an edge surface of the glass or glass-ceramic substrate and the second surface of the coating is roughened; and a polymer covering disposed on at least a portion of the second surface of the surface-roughened coating, wherein the surface roughened coating comprises a component for mechanically binding with the polymer covering and a component for chemically binding with the glass or glass-ceramic substrate, and wherein the mechanical binding component comprises particles added to, and exposed on, at least the second surface of the surface-roughened coating.
