ITEM 8.01      OTHER EVENTS

         On October 4, 2005, Cytec Industries Inc. (the "Company") closed its
sale of $250,000,000 aggregate principal amount of its 5.500% Notes due 2010 and
$250,000,000 aggregate principal amount of its 6.000% Notes due 2015 (together,
the "Notes") pursuant to an Underwriting Agreement, dated September 29, 2005,
among the Company, Citigroup Global Markets Inc., ABN AMRO Incorporated and
Wachovia Capital Markets, LLC, as representatives of the several Underwriters
named in Exhibit A thereto. The Notes were issued pursuant to an Indenture,
dated as of March 15, 1998, as amended by the First Supplemental Indenture,
dated as of May 11, 1998, between the Company and JPMorgan Chase Bank, National
Association, as successor to PNC Bank, National Association, as trustee.
Interest on the Notes is payable semi-annually on April 1 and October 1 of each
year, beginning on April 1, 2006. The Notes have been registered under the
Securities Act of 1933 (the "Act") pursuant to registration statements on Form
S-3 (File Nos. 333-51876 and 333-127507) previously filed with the Securities
and Exchange Commission under the Act.

         The aggregate net proceeds received by the Company from the sale of the
Notes were approximately $495,852,500, after deducting the underwriting
discount. The Company intends to use the net proceeds to repay all amounts
outstanding under its 364-day credit facility and revolving credit facility,
which, as of September 16, 2005, were approximately $426.8 million and $67.7
million, respectively. The Notes are the Company's senior unsecured obligations
and will rank equally with all of its other unsecured and unsubordinated
indebtedness. The notes will be effectively subordinated to all secured
indebtedness of the Company to the extent of the assets securing such
indebtedness. The notes will be structurally subordinated to all obligations of
the Company's subsidiaries, including claims with respect to trade payables.
