Rohm and Haas to Build Plant in Vietnam

• Nhon Trach facility will serve fast-growing decorative coatings market here

• Company to spend US$10 million for around 25,000 metric ton facility

• New site to join network of 11 plants across Asia-Pacific Region

• Rohm and Haas committed to always bringing leading technology to Southeast Asia in support of customer growth and needs

May 28th 2008--Rohm and Haas Company (NYSE:ROH) said today that it intends to build an acrylic emulsion facility in Nhon Trach city, within the Dong Nai province of Vietnam, in order to meet the fast-growing needs for the paints and coatings market. The company will spend approximately US$10 million for this facility, which will be completed by the middle of 2009 and will join a network of 12 plants across the Asia-Pacific region, part of a system of 34 plants worldwide.

“This is a great investment for Rohm and Haas, one that has significant strategic benefits,” said Bruce Hoechner, Vice President and Asia-Pacific Regional Director for the $2 billion Paint and Coatings Materials business. “We have been importing products into the Vietnamese market for more than 12 years, trying to keep up with demand by bringing in products from operations in China and Thailand,” he said. “However, demand continues to grow, and is now expected to grow at 15 percent per year for the next 10 years. We simply must build a plant here now in order to serve the growing needs of our customers.”

Rohm and Haas has gained remarkable reputation in Vietnam for excellent products, tailored to meet specific customer needs. Rohm and Haas will be bringing its state of art manufacturing capability to Nhon Trach, with the ability to expand capacity as needed to meet future market demand. Technical support will continue to be provided from the technical service lab in Singapore and the state-of-the-art R&D center in Shanghai, China. Hoechner said the new Vietnam facility will strengthen the efficiency and capabilities of the entire Asia-Pacific supply chain.

The plant will be constructed within the Nhon Trach 3 Industrial Park, about 30 kilometers from Ho Chi Minh City.

Within the past six months, Rohm and Haas has commissioned new plants in Sanshui, Foshan, China and Chennai, India, and expanded a facility in Taloja, India. The company is also building or expanding plants in Russia, Turkey and Mexico.
