   Quaker Chemical Expects Full-Year Earnings to Be Lower Than Prior Guidance

    CONSHOHOCKEN, Pa., Oct. 14 /PRNewswire-FirstCall/ -- Quaker Chemical
Corporation (NYSE: KWR) today announced that it expects full-year earnings to
be below previous guidance of around $1.52 per share.  A review of preliminary
third quarter earnings indicates that profits for the quarter will be
considerably lower than the Company's expectations, and it is unlikely that
fourth quarter earnings recovery will be sufficient to reach previous full-
year guidance.
    Ronald J. Naples, Chairman and Chief Executive Officer, commented, "It has
become clear that the key factors upon which our prior earnings guidance for
the year was predicated have not advanced at the expected pace, and our third
quarter profits are lower than planned.  Certainly, unexpected dramatic
increases in the price of oil have been a factor.  We are continuing to
analyze third quarter earnings and are assessing full-year implications.  It's
important to note that we are staying focused on controlling raw material
costs, implementing price increases to offset raw material costs, advancing
Quaker product conversions in our CMS business, and building volume."
    As previously announced, the Company expects to release its third quarter
earnings on October 28, 2004 (after market close) to be followed by an
investor conference call to discuss third quarter results on October 29, 2004
at 2:30 p.m. (ET).  Access the conference by calling 877-269-7756 (toll free)

    Quaker Chemical Corporation, headquartered in Conshohocken, Pennsylvania,
is a worldwide developer, producer, and marketer of custom-formulated chemical
specialty products and a provider of chemical management services for
manufacturers around the globe, primarily in the steel and automotive
industries.

    This release contains forward-looking statements that are subject to
certain risks and uncertainties that could cause actual results to differ
materially from those projected in such statements.  A major risk is that the
Company's demand is largely derived from the demand for its customers'
products, which subjects the Company to downturns in a customer's business and
unanticipated customer production shutdowns.  Other major risks and
uncertainties include, but are not limited to, significant increases in raw
material costs, customer financial stability, worldwide economic and political
conditions, foreign currency fluctuations, and future terrorist attacks such
as those that occurred on September 11, 2001.
