Item 2.01 Completion of Acquisition or Disposition of Assets

As reported on Form 8-K dated March 4, 2005, Cytec Industries Inc. (the
"Company") completed its acquisition of the Surface Specialties business
("Surface Specialties") of UCB S.A. ("UCB") on February 28, 2005. Item 2.01 of
this Form 8-K/A is being filed in order to present the unaudited pro forma
condensed combined historical statement of income of the Company for the year
ended December 31, 2004 and the audited Combined Special Purpose Financial
Statements of Surface Specialties (A business of UCB Group) as of December 31,
2004 and 2003 and for the years then ended. Additionally, under Item 7.01 below,
the Company is furnishing as supplemental information, unaudited pro forma
condensed combined historical quarterly statements of income for each of the
quarters ended March 31, 2004, June 30, 2004, September 30, 2004, December 31,
2004 and March 31, 2005 as Exhibit 99.3 included herein.

This amendment modifies and supplements the Current Report on Form 8-K,
filed by the Company with the Securities and Exchange Commission on March 4,
2005.

Rule 3-05 of Regulation S-X requires that the financial statements
specified in Rules 3-01 and 3-02 of Regulation S-X be provided for Surface
Specialties as an acquired business meeting the criteria specified in those
rules. Due to circumstances related to the business of Surface Specialties, it
was impracticable to have prepared complete financial statements in accordance
with all the technical requirements of these rules. In particular, UCB had never
prepared financial statements in accordance with US GAAP. Surface Specialties
was operated by UCB as part of a segment including their Chemicals and Film
sectors and never prepared stand-alone financial statements for Surface
Specialties. In addition, the independent auditors for UCB have never audited or
reported separately on the operations, net assets or cash flows of Surface
Specialties. Another issue that makes full compliance with Rule 3-05 of
Regulation S-X impracticable relates to UCB's acquisition of the resins,
additives and adhesives business (the "Solutia Business") of Solutia, Inc.
("Solutia") in January 2003. The preparation of separate audited financial
statements for the Solutia Business for 2002 would be impracticable to obtain
since UCB, upon acquiring the Solutia Business, was not required by Belgium GAAP
to present separate audited 2002 financial statements for the Solutia Business
and accordingly, none were prepared. Solutia, like UCB, did not report segment
financials for the business sold. In addition, UCB informed the Company that
they do not have a contractual right to obtain audited financial statements from
Solutia and this compounded by the fact that Solutia has been in bankruptcy
(Chapter 11) since December 2003 with significant turnover in top management
positions, makes it impracticable for the Company to have prepared complete 2002
audited financial statements for the Solutia Business. The Company requested
from the Securities and Exchange Commission concurrence that the financial
information filed herewith along with the consolidated balance sheet as of March
31, 2005, filed on the Company's 10-Q for the period ended March 31, 2005 which
was filed on May 10, 2005, would fully satisfy the requirements of Rule 3-05 of
Regulation S-X and received the Staff's response that it did not object to the
Company's proposal.
