Ceramic enamel (frit) is an opaque, decorative border found along the periphery of glass windshields used in passenger and commercial transportation vehicles, as well as, architectural spandrel and decorative glass applications. In transportation and architectural applications, the primary function of ceramic enamel is to conceal aesthetically unpleasing, but essential structural components and to prevent photodegradation of the underlying polyurethane adhesive, which is used to bond glass windows into supporting structures. Typically, ceramic enamels are applied by screen printing ceramic slurry onto the glass substrate, which is subsequently fired in a furnace during the glass-forming process. The fired enamel is then primed with solvent-based primer(s) to facilitate adhesion between the enamel and polyurethane adhesive.
