                QUAKER CHEMICAL ANNOUNCES RECORD QUARTERLY SALES
                             AND NET INCOME GROWTH

CONSHOHOCKEN,   Pa.,  April  29   /PRNewswire-FirstCall/   --  Quaker   Chemical
Corporation  (NYSE: KWR) today announced record quarterly sales of $98.1 million
and net income growth of 7% for the first quarter ended March 31, 2004.

First Quarter 2004 Summary
- --------------------------

Net  income for the first  quarter  increased  7% to $3.3  million  versus  $3.1
million  for the first  quarter  of 2003.  Consistent  with  previous  guidance,
earnings  per  diluted  share were $0.33 in the first  quarters of both 2004 and
2003.

Net sales for the first quarter of 2004 were a record $98.1 million, up 34% from
$73.3 million for the first quarter of 2003.  Foreign exchange rate translation,
the Company's 2003  acquisitions  and the Company's  recently  awarded  chemical
management  services  (CMS)  contracts  favorably  impacted  net  sales  by $6.5
million, $5.5 million and $10.1 million,  respectively.  The remaining net sales
increase of  approximately  4% is primarily  due to double-  digit growth in the
Asia/Pacific and South American regions.

Gross margin as a percentage of sales  declined from 38.7% for the first quarter
of 2003 to 33.1% for the first  quarter of 2004. As  previously  disclosed,  the
Company's new CMS contracts have caused different  relationships between margins
and revenue than in the past. At the majority of current CMS sites,  the Company
effectively acts as an agent and records revenue and costs from these sales on a
net  sales or  "pass-through"  basis.  The new CMS  contracts  have a  different
structure,  which  results in the Company  recognizing  in reported  revenue the
gross revenue received from the CMS site customer, and in cost of goods sold the
third party product purchases. The negative impact to gross margin for the first
quarter related to the new CMS contracts is  approximately 5 percentage  points.
The  remaining  decline  in  gross  margin  as a  percentage  of sales is due to
increased raw material costs, as well as product and regional sales mix.

Selling,  general and  administrative  expenses for the quarter  increased  $3.9
million compared to the first quarter of 2003. Foreign exchange rate translation
and the  Company's  2003  acquisitions  accounted for  approximately  60% of the
increase  over the prior  year.  The  majority  of the  remaining  increase  was
primarily   due  to  higher   expenses   associated   with  the   Company's  ERP
implementation, Sarbanes-Oxley compliance, as well as inflationary increases.

The increase in other income reflects a  priority-return  distribution  from the
Company's  real estate  joint  venture in the first  quarter of 2004 and foreign
exchange  gains in the first  quarter of 2004 versus losses in the first quarter
of 2003.  The increase in net interest  expense is primarily  due to higher debt
balances outstanding during the first quarter of 2004 versus the prior year.

Balance Sheet and Cash Flow Items - --------------------------------- The Company's debt-to-total capital ratio remains strong at 37% at the end of the first quarter of 2004 compared to 34% at the end of 2003. The higher accounts receivable and inventory at the end of the first quarter are primarily due to the Company's new CMS contracts and increased sales volume. In the first quarter of 2004, capital expenditures were $2.3 million, primarily related to the Company's U.S. lab renovation and global ERP implementation. Outlook - ------- Ronald J. Naples, Chairman and Chief Executive Officer, commented, "The first quarter results were consistent with our expectations. We are seeing signs of an improving global economy with sequential quarterly growth in all four regions and especially high growth in the South American and Asia/Pacific markets. However, partially offsetting the positive impact of this growth is the continuation of high raw material costs as well as higher expenses that are primarily a result of higher pension, insurance, Sarbanes-Oxley compliance and ERP implementation expenses." Mr. Naples continued, "Our view of the world really hasn't changed from our last guidance. We expect 2004 to be a strong revenue growth year in all business segments and in all regions due to our business initiatives as well as an improvement in the global economy. However, we also continue to expect to be negatively impacted by high crude oil prices as well as the higher SG&A costs related to the items above and the restoration of performance-based incentive compensation. Our 2004 outlook continues to be for a slight improvement in year-over-year earnings. For the second quarter, we expect earnings to be similar to 2003, and we are moving ahead with important business initiatives. The recent increase of our dividend, the 32nd consecutive year of annual dividend increases to shareholders, is a tangible sign of our confidence in the prospects of the Company and our commitment to delivering value for our shareholders." 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. As previously announced, Quaker Chemical's investor conference call to discuss first quarter results is scheduled for April 30, 2004 at 2:30 p.m. (ET).
