                Quaker Chemical Announces Record Quarterly Sales

October 30, 2003

CONSHOHOCKEN, PA -- For its third quarter, Quaker Chemical Corporation (NYSE:
KWR) today announced record quarterly sales of $89.7 million and earnings per
diluted share of $0.42, a 17% increase over the second quarter of 2003 earnings
per diluted share.

Third Quarter Summary
- ---------------------

Net income for the third quarter was $4.1 million versus $4.3 million for the
third quarter of 2002, or $0.42 per diluted share versus $0.45 per diluted share
in the prior year period. On a sequential basis, third quarter net income
increased 19% over the second quarter's net income of $3.5 million.

Net sales for the third quarter were a record $89.7 million, up 22% from $73.3
million for the third quarter 2002. Foreign exchange rate translation and the
Company's 2003 acquisitions favorably impacted net sales by $4.8 million and
$1.3 million, respectively. Third quarter sales also include approximately $9.7
million from the Company's recently awarded chemical management services (CMS)
contracts, which were effective May 1, 2003. The remaining part of the net sales
increase of approximately 1% is primarily due to double-digit growth in the Asia
Pacific and South America regions offset by a decline in business in the U.S.

Gross margin as a percentage of sales declined from 40.1% for the third quarter
of 2002 to 34.3% for the third quarter of 2003. 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, which substantially offset each other. The
negative impact to gross margin for the third quarter related to the new CMS
contracts is approximately 4 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. The Company continues to expect raw material
prices to remain at these levels in the near term due to sustained high oil
prices.

Selling, general and administrative expenses for the quarter increased $1.8
million or 8% compared to the third quarter of 2002. Approximately $1.4 million
of the increase is due to foreign exchange rates and the Company's 2003
acquisitions. Increases in other expenses, including pension and the Company's
continued rollout of its global ERP system, were largely offset by reduced
incentive compensation expense.

Other income was lower primarily due to foreign exchange gains in 2002 as a
result of the weakening of the Brazilian real and its impact on the U.S. dollar
denominated cash balances in Brazil.

The year-to-date effective tax rate was reduced to 30% in the third quarter
primarily due to the Company's favorable settlement of several outstanding tax
audits and appeal issues.

Ronald J. Naples, Chairman and Chief Executive Officer, stated, "Though our
overall earnings level is consistent with our previous guidance, we continue to
see softer than expected demand for our products and services to the steel
industry in the U.S. and Europe. In the third quarter, this was somewhat offset
by significant growth in our Brazilian and South American markets, lower overall
tax rates, and lower incentive compensation. In addition, we continue to be
negatively impacted by higher raw material prices primarily due to continued
high crude oil prices."

Mr. Naples continued, "While we continue to see short-term challenges in front
of us, we are also making significant strides with our key strategic
initiatives. In 2003, we have now made three tight-fit acquisitions, including
the recently announced acquisition of the Cincinnati-Vulcan steel business. All
of these acquisitions bring key customer relationships and product technology,
enabling us to enhance our already strong market positions. In addition, all
three are expected to be slightly accretive to earnings in the short term and
more significant profit contributors longer term. Also, we continue to grow our
CMS business and have recently been awarded another two major auto CMS sites
that are in addition to the seven new sites we started up in May. And finally,
during the last 12 months we have implemented our global ERP system at four of
our largest sites in Holland, Spain, and the U.S. We believe all of the above
initiatives are key steps in helping us achieve our longer-term business
strategies."

Year-to-Date Summary
- --------------------

Net income for the first nine months of the year was $10.7 million versus $9.9
million in the first nine months of 2002. Earnings per diluted share increased
6% to $1.11 versus $1.05 in the first nine months of 2002.

Net sales for the first nine months of the year increased to $246.5 million, up
22% from $202.7 million for the first nine months of 2002. Foreign exchange rate
translation and timing of the Company's 2002 and 2003 acquisitions favorably
impacted net sales by $11.1 million and $9.5 million, respectively. Net sales
for the first nine months of the year also include approximately $17.1 million
from the Company's new CMS contracts. The remaining part of the net sales
increase of approximately 3% is primarily due to double-digit growth in the Asia
Pacific and South America regions offset by a decline in business in the U.S.

Gross margin as a percentage of sales declined from 40.8% for the first nine
months of 2002 to 35.7% for the first nine months of 2003. The Company's new CMS
contracts negatively impacted gross margin for the first nine months of 2003 by
approximately 3 percentage points with the remaining decline due to increased
raw material costs, as well as product and regional sales mix.

Selling, general and administrative expenses for the first nine months of 2003
increased $4.4 million from the first nine months of 2002. $4.3 million of the
increase is due to foreign exchange rates and the Company's acquisitions. The
remainder of the increase is primarily due to higher pension costs and the
Company's continued implementation of its global ERP system partially offset by
reduced incentive compensation expense.

Balance Sheet and Cash Flow items
- ---------------------------------

The Company's debt to total capital ratio remains strong at 31% at the end of
September, 2003 compared to 25% at the end of 2002 and 35% at the end of
September, 2002. As of the end of September 2003, the Company had approximately
$26 million outstanding on its credit lines, which have a maximum borrowing
capacity of $50 million.

As previously disclosed, the Company received $4.2 million of priority cash
distributions from its real estate joint venture in the first half of 2003. In
addition, the higher accounts receivable at the end of September 2003 is
primarily due to the increased sales attributable to the Company's new CMS
contracts, foreign exchange rate changes and higher sales volumes.

Outlook
- -------

Mr. Naples stated, "We do expect to see some pickup in business volumes in the
fourth quarter primarily due to market share gains. However, this expectation is
tempered by what we still see as significant demand uncertainty in many of our
key markets for the fourth quarter as well as into next year. For example, we
are getting signals that some of our customers may take longer than normal
shutdowns in December. While our visibility is not clear, the net of all this is
that we continue to estimate that our fourth quarter earnings will be similar to
the third quarter. Despite the near-term struggles for earnings growth, we are
confident that the strategic steps we have taken this year, as well as our
strong balance sheet and dividend yield, put us in an excellent long-term
position to continue to build our business, and hence, enable us to continue to
create significant long-term value for both our customers and 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 uncertainties related to downturns in a customer's
business and unanticipated customer production planning curtailments. 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
third quarter results is scheduled for October 31, 2003 at 10:00 a.m. (ET).
