  Quaker Chemical Announces Record Quarterly Sales and Increased Earnings

   May 5, 2003

   CONSHOHOCKEN, PA -- Quaker Chemical Corporation (NYSE: KWR) today announced
record quarterly sales of $73.3 million and net income growth of 32% for the
first quarter ended March 31, 2003.

   1st Quarter 2003 Summary
   ------------------------
   Net income for the first quarter was $3.1 million versus $2.4 million for
the first quarter 2002.  The earnings per diluted share of $0.33 was a 27%
improvement over the first quarter 2002 result of $0.26 per diluted share.
   Net sales for the first quarter were a record $73.3 million versus
$59.9 million for the first quarter 2002.  Foreign exchange rate translation
and the timing of the Company's 2002 acquisitions favorably impacted net sales
for the quarter by approximately $2.0 million and $5.6 million, respectively.
Excluding the impact of foreign exchange rate translation and the timing of
the Company's 2002 acquisitions, net sales would have been $65.7 million or
9.6% above the prior year.  Net sales in all regions except Europe increased
on a local currency basis, showing improvements in both volume and price/mix.
   Gross margin as a percentage of sales declined from 40.6% for the first
quarter 2002 to 38.7% for the first quarter 2003 primarily due to increased
raw material costs and product mix.  As previously disclosed, the Company
expects raw material prices to be higher in 2003, especially in the first
half, due to higher oil prices experienced earlier in the year.
   Selling, general and administrative expenses increased $2.7 million over
the first quarter 2002.  Timing of the Company's 2002 acquisitions and foreign
exchange rate translation accounted for approximately two-thirds of the
increase.  As previously disclosed, increased costs related to pension,
insurance, and the Company's ERP implementation, accounted for the remaining
increase.

   Outlook
   -------
   Ronald J. Naples, Chairman and Chief Executive Officer, commented, "This
first quarter gets us off to a good start in 2003, a year that still looks to
us as one that will be characterized by shifting and uncertain manufacturing
demand.  We have seen some recent softness in key markets that could
negatively affect our volumes, and higher raw material costs will continue to
be a factor.  We expect the stronger euro will help us out, though, as will
cost control.  On balance, we continue to expect year-over-year earnings
growth in 2003.  We expect that the second quarter will contribute to this
improvement over prior year, if only slightly given the CMS contract start-up
costs expected in the quarter that are linked to our recently announced GM
award."

   New CMS Contracts
   -----------------
   As previously announced in the Company's April 11, 2003 press release,
Quaker has been awarded a series of multi-year contracts to provide chemical
management services (CMS) for General Motors Powertrain manufacturing sites.
These contracts will be implemented during the second quarter of 2003.  In
addition, DaimlerChrysler has also recently awarded the Company a CMS contract
for its Trenton Engine plant.
   Mr. Naples stated that, "This new business is an important step in
building the Company's share and leadership position in the automotive process
fluids market and will position the Company well for penetration of CMS
opportunities in other metalworking manufacturing markets.  Over the next few
months, we may have to absorb the transition and start-up costs of these
contracts, which will hurt a bit, but the long-term prospects of creating
value for our customers and us is very real."
   For 2003, the earnings impact due to the new CMS sites is expected to be
immaterial due to transition and start-up costs, largely in the second
quarter.  Future profitability of the contracts will be based on Quaker's
ability to identify and implement cost reduction programs and product
conversions.  In addition, the new contracts will result in an increased
investment of working capital estimated to be $4 million, although this amount
will be dependent on the final terms negotiated with suppliers.
   These new contracts will cause future income statements to show different
relationships between margins and revenue than in the past.  At the majority
of current CMS sites, the Company effectively acts as an agent for the
customer whereby it purchases chemicals from other companies and resells the
product to the customer at little or no margin.  The revenue and costs from
these sales are reported on a net sales or "pass-through" basis.  The
structure of the new GM Powertrain site contracts is different in that the
Company's revenue received from the customer will be in the nature of a fee
for products and services provided to the customer, which are indirectly
related to the actual costs incurred.  As a result, the Company will recognize
in reported revenues the gross revenue received from the CMS site customer,
and in cost of goods sold, the third party product purchases, which will
substantially offset each other.  This will result in a significant increase
in the Company's reported revenue, estimated to be approximately $35-$40
million on an annualized basis, the profitability of which will be dependent
upon Quaker's ability to identify and implement cost reduction programs and
product conversions.
   In addition, the Company is currently negotiating similar contract
structures for some of its existing CMS sites.  It is possible that this will
also require the Company to recognize an additional $10-$15 million in
annualized sales starting in the second quarter.

   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.  Such risks and
uncertainties include, but are not limited to, further downturns in our
customers' businesses, significant increases in raw material costs, worldwide
economic and political conditions, the impact of SARS, foreign currency
fluctuations, and future terrorist attacks such as those that occurred on
September 11, 2001.

first quarter earnings results is scheduled for May 6, 2003, at 2:30 p.m.
