PPG to sell fine chemicals business for approximately $65 million

Date: 19 September 2007

PPG Industries has signed an agreement with ZaCh System S.p.A., the fine chemicals subsidiary of Zambon Company S.p.A., Milan, Italy, under which the company would divest its fine chemicals business for approximately $65 million.

The transaction would include a book charge to income of less than $0.15 per share. Completion of the transaction is expected in the fourth quarter and is subject to customary closing conditions, including discussions with appropriate employee representative bodies in Europe and receipt of required regulatory approvals.

“Following last week’s announcement of our potential divestiture of our auto glass businesses, this transaction is yet another step toward achieving PPG’s vision of continuing to be the leading coatings and specialty products and services company,” said Charles E. Bunch, PPG chairman and chief executive officer.

“The acquisition of PPG’s fine chemicals business is consistent with Zambon Company’s continuing desire to expand its global presence,” said Gianni Marini, ZaCh System board chairman and Zambon Company board member. “We are quite pleased to acquire a PPG business that is recognized as a technology leader, with manufacturing locations in Europe and the United States, reinforcing our custom synthesis business strategy and the value of Zambon research competence.”

PPG facilities included in the agreement are a pharmaceutical fine chemicals plant in LaPorte, Texas, and the PPG-Sipsy facility in Avrille, France. The pharmaceutical fine chemicals plant in LaPorte operates separately from PPG’s adjacent phosgene derivatives facility there, of which PPG will retain operation. The fine chemicals business employs approximately 360 people.

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, and its current reports on Form 8-K, 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 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, the impact of environmental regulations, unexpected business disruptions 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.
