PPG Industries has announced a marketing alliance with Walker Glass Co Ltd of Montreal, Canada. The two companies will jointly market the Walker Textures line of acid-etched glass & mirrors with Starphire ultra-clear glass by PPG. Acid-etched, or frosted, glass is created when an aqueous solution of hydrofluoric acid is applied to a glass surface, resulting in a smooth satin appearance or a matted translucent appearance. Walker Glass, the only North American manufacturer of acid-etched glass, currently produces its full-surface, acid-etched Walker Textures line in satin, velour & opaque finishes. Acid-etched glass products are typically used for dividing walls, wall coverings, office partitions, show & bath enclosures, doors, display shelving & other interior applications. They also can be used for exterior uses such as insulating glass units.
