To Shareholders of Quaker Chemical Corporation

     This letter refers to our Notice of Annual Meeting of
Shareholders and Proxy Statement dated March 31, 1994 (the
"Materials").  On page 9 of the Materials there is a chart that
bears the caption "LONG-TERM INCENTIVE PLAN -- AWARDS LAST YEAR."
Certain information included in the chart relating to Messrs. Peter
A. Benoliel and Sigismundus W. W. Lubsen is incorrect.  Although we
do not regard the errors as material, we have decided to provide
you with a revised chart, which is printed on the reverse side of
this letter.

     If you have already returned your Proxy and if, after
reviewing the revised chart, you wish to change your vote, you may
do so by submitting a new Proxy.  A new Proxy may be obtained for
this purpose by calling Ms. Kathleen Mague, Assistant Secretary,
toll free, or by making this request by facsimile or letter, as
follows:

          By telephone:  1-800-523-7010

     Upon receiving your request, we will promptly mail you another
Proxy.  To be counted, the Proxy must be received prior to the
Annual Meeting scheduled for May 4, 1994.

(1) Performance Incentive Units

(2) The value on maturation of a performance incentive unit is determined
    by performance over a four (4) year period as plotted on a grid defined
    by two axes; one axis sets forth variable rates of return on equity,
    and one axis sets forth variable rates of income before tax as a
    percentage of sales.  Each performance unit is issued at the value of
    the stock price of incentive stock options ($21.00, except as to
    certain options granted to Messrs. Benoliel and Lubsen where the
    option price is $22.00), and the 1993 performance unit grid results in
    a zero payout for performance of less than 9% return on equity and less
    than 7% income before tax as a percentage of sales.  A payout of $21.00
    per unit (or $22.00 per unit as to certain units granted to Messrs.
    Benoliel and Lubsen) will be made if performance reaches the target,
    and a payout of $42.00 per unit (or $44.00 per unit as to certain units
    granted to Messrs. Benoliel and Lubsen) will be made if performance
    reaches the maximum of the measurement scale.  While it is difficult to
    calculate the amount of any future payments using an example where a
    return on equity is 10% and income before tax as a percentage of sales
    is less than 7%, a minimum payment of $16,000, $21,125, $15,750, and
    $13,125 would be payable to Messrs.  Benoliel, Lubsen, Meijer, and
    Burrows, respectively.  Mr. Dolich retired on December 31, 1993 and
    will be eligible to receive a 25% pro rata share of the actual future
    minimum payout, currently estimated to be nil.
