PPG offers outlook on fourth quarter 2006 chlor-alkali earnings

PITTSBURGH, Nov. 16, 2006 – PPG Industries (NYSE:PPG) expects operating earnings from its chlor-alkali business in the fourth quarter 2006 to be reduced in the range of $35 million to $40 million, or $0.13 to $0.15 per share, versus the third quarter 2006 due primarily to lower expected volumes and lower pricing.

The company stated that it had recently received notification from several significant chlor-alkali chemical customers of extensive facility shutdowns or production curtailments for November and December. PPG did not disclose the customers from which it has received notification.

The company stated that it expects chlor-alkali volumes to return to more normal levels in the first quarter of 2007.

Forward-Looking Statements
Statements in this news release relating to matters that are not historical facts are forward-looking statements reflecting the company's current view with respect to future events or objectives and financial or operational performance or results. These matters involve risks and uncertainties as discussed in PPG Industries' periodic reports on Form 10-K and Form 10-Q filed with the Securities and Exchange Commission. Accordingly, many factors could cause actual results to differ materially from the company's forward-looking statements.
Among these factors are unforeseen changes in our customers' businesses or in the demand for our products, increasing price and product competition by foreign and domestic competitors, fluctuations in cost and availability of raw materials and energy, the ability to maintain favorable supplier relationships and arrangements, economic and political conditions in international markets, foreign exchange rates and fluctuations in such rates, and the unpredictability of possible future litigation, including litigation that could result if the asbestos settlement discussed in PPG's filings with the SEC does not become effective. However, it is not possible to predict or identify all such factors. Consequently, while the list of factors presented here is considered representative, no such list should be considered to be a complete statement of all potential risks and uncertainties. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements.
Consequences of material differences in results as compared with those anticipated in the forward-looking statements could include, among other things, business disruption, operational problems, financial loss, legal liability to third parties and similar risks, any of which could have a material adverse effect on PPG's consolidated financial condition, operations or liquidity.
