Quaker Chemical Acquires D.A. Stuart's U.S. Aluminum Hot Rolling Oil Business

Quaker becomes a leading player in the U.S. market

CONSHOHOCKEN, Pennsylvania, July 19, 2010 - Quaker Chemical Corporation (NYSE: KWR) announced on Friday it has
acquired D.A. Stuart's U.S. aluminum hot rolling oil business from Houghton
International, including the rights to sell the product portfolio
internationally. With this acquisition, Quaker becomes a leading player in
the US aluminum hot rolling market, serving some of the largest reversing
mills, single and multi-stand tandem finishing mills, and combination mill
systems in the country. The acquired business had net sales in 2009 of
approximately US$7 million.

Michael F. Barry, Quaker's Chairman, Chief Executive Officer and
President, commented, "This business is a strategic fit for Quaker because it
is complementary to our existing business, is aligned with our core
competencies of lubrication and surface treatment, and will facilitate growth
in our primary metals business both within and outside of North America. The
aluminum hot rolling market has strong long-term growth prospects, especially
in emerging economies such as Russia, South America, Eastern Europe, the
Middle East and Asia. Quaker currently has a presence in those countries and
is well positioned for growth."

Quaker will expand its current product portfolio by adding the
B-SERIES(R), ALUSHIELD(R) and other aluminum hot mill rolling oils. The
addition of these products, combined with the existing QUAKEROL(R)
lubricants, will enable Quaker to offer a more comprehensive package to
customers worldwide. Quaker will be able to tailor a rolling product to meet
the unique needs of a mill for the entire sheet producing process - from
casting to finishing. Aluminum producers looking to source their varied
lubricant needs from a single supplier can now turn to Quaker.

Mr. Mark Bohr, formerly General Manager of Aluminum Rolling-USA at D.A.
Stuart, will lead the business for Quaker.
