                  Re:      Cytec Industries Inc.:
                           Registration Statement No. 333-127507

Dear Ms. Long:

                  On behalf of Cytec Industries Inc. (the "Company"), as issuer
under the above referenced registration statement (the "Registration
Statement"), request is hereby made that the effective date of the Registration
Statement be accelerated so that it will become effective at 3:00 p.m. on
September 19, 2005, or as soon thereafter as is possible.

                  In requesting acceleration of effectiveness of the
Registration Statement, the Company acknowledges that:

     (1)  should the Securities and Exchange  Commission (the  "Commission")  or
          the staff, acting pursuant to delegated authority,  declare the filing
          effective, it does not foreclose the Commission from taking any action
          with respect to the filing;

     (2)  the  action  of  the  Commission  or the  staff,  acting  pursuant  to
          delegated  authority,  in  declaring  the filing  effective,  does not
          relieve the Company from its full  responsibility for the adequacy and
          accuracy of the disclosure in the filing; and

     (3)  the Company  may not assert  staff  comments  and the  declaration  of
          effectiveness  as  a  defense  in  any  proceeding  initiated  by  the
          Commission  or any person  under the  federal  securities  laws of the
          United States.

                                                     Very truly yours,

                                                     /s/ James M. Young
