Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

On April 12, 2012, Cytec UK Holdings Ltd. (“Cytec UK”), a private limited company incorporated in England and Wales which is indirectly wholly-owned by Cytec Industries Inc. (“Cytec”), issued an announcement (the “Rule 2.7 Announcement”) pursuant to Rule 2.7 of the United Kingdom City Code on Takeovers and Mergers (the “City Code”) disclosing that Cytec UK and the Board of Umeco plc, a public limited company incorporated in England and Wales (“Umeco”) had agreed on the terms of a recommended cash offer of 550 pence per share (the “Offer”) to be made by Cytec UK for the acquisition of the entire issued and to be issued share capital of Umeco. The Offer values Umeco’s issued and to be issued share capital at approximately £274 million (approximately $439 million based upon an exchange rate of 1.60 (the “Offer Consideration”)). The acquisition is to be effected by way of a scheme of arrangement under UK law which requires the approval of a UK court and approval of a majority of Umeco’s shareholders in number present in person or by proxy at the Court meeting representing at least 75% of the votes cast. The scheme is also subject to receipt of certain regulatory approvals and other customary conditions. The transaction is expected to close in the third quarter of 2012.

In connection with the Offer, Cytec and Cytec UK, have entered into an agreement (the “Barclays Agreement”) with Barclays Bank PLC, acting as financial advisor (“Barclays”), to provide Barclays with certain assurances, confirmations and undertakings in support of the Offer, to enable Barclays to confirm that sufficient cash resources are available to Cytec UK to satisfy in full the Offer Consideration, and to permit Barclays to fulfill its responsibilities under the City Code. Cytec’s responsibilities under the Barclays Agreement include effectively restricting the use of the funds required to satisfy the sterling amount of the consideration payable under the Offer (including provisioning for exchange rate movements) until the earlier of the Offer completion or termination. Cytec drew down $210 million from its existing revolving credit facility for the purposes of funding the Offer, such amount being subject to the aforementioned restrictions.

The foregoing summary of the Offer and the transactions contemplated thereby does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Rule 2.7 Announcement, which is attached as Exhibit 99.1, to this Current Report on Form 8-K and incorporated herein by reference.

See information contained in the press release dated April 12, 2012 (“Press Release”) furnished herewith as Exhibit 99.2.

On April 12, 2012, Cytec will hold an investor conference call in connection with the Offer, Press Release and the transactions described therein. A copy of the Press Release and the slides to be referenced on the investor conference call are attached hereto as Exhibits 99.2 and 99.3, respectively. The information contained in Exhibits 99.2 and 99.3 hereto shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (“Exchange Act”) or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Exchange Act, except as expressly set forth by specific reference in such filing.
