Walker Glass and PPG form marketing alliance for acid-etched decorative glass

PITTSBURGH, March 24, 2008 – PPG Industries (NYSE:PPG) has announced a marketing alliance with Walker Glass Co., Ltd., of Montreal. The two companies will jointly market the Walker Textures line of acid-etched glass and 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 three finishes: satin, velour and opaque. These products also are available in Walker Textures Select glass – custom partial-sheet etched products – and Walker Textures Nuance glass – a series of patterned etched products to be launched March 31.

Acid-etched glass products are typically used for dividing walls, wall coverings, office partitions, show and bath enclosures, doors, display shelving and other interior applications. They also can be employed for exterior uses such as insulating glass units. Starphire glass is ideal for use with Walker Textures glass because of its clarity and color fidelity.

The alliance between Walker Glass and PPG is designed to take advantage of the enhancements Starphire glass and Walker Textures glass offer each other. It will enable the companies to leverage each other’s marketing efforts to the U.S. and Canadian design communities.

Walker Glass Co., Ltd., joins IIMAK, Amherst, N.Y., and ICD High-Performance Coatings, Vancouver, Wash., as PPG marketing alliance partners.
