Cytec Announces Update to Operating Segments

Woodland Park, New Jersey, June 3, 2009 – Cytec Industries Inc. (NYSE:CYT) announced today a change in its business segment reporting structure to align with the organizational changes implemented in the second quarter 2009. The new reporting structure will provide greater clarity on the new strategic focus of the company. As a result, Cytec now has five reportable operating segments.

The Cytec Specialty Chemicals business will now consist of three operating segments: Coating Resins, Additive Technologies, and In Process Separation. Coating Resins, previously called Surface Specialties, consists of the Liquid Coatings Resins, Radcure, and Powder Coating Resins product lines. Now included in Liquid Coating Resins are our Urethane Resins products, previously part of the former Performance Chemicals segment.

In Process Separation is comprised of the Mining Chemicals and Phosphine Chemicals product lines, also previously included in the former Performance Chemicals segment.

Engineered Materials is comprised of Advanced Composites, Carbon Fiber, and Structural Film Adhesives, and now includes the Pressure Sensitive Adhesives and Formulated Resins product lines which were both previously included in the former Performance Chemicals segment. These additional product lines incorporated into the Engineered Materials segment will provide the foundation for a High Performance Industrial Materials market focus. The Building Block Chemicals segment remains unchanged.

Shane Fleming, Chairman, President, and Chief Executive Officer said, “While 2009 continues to be challenging year for us, I am confident that the realignment of our operating segments is the right operating model to implement our long-term strategy more effectively. We are focusing on building on our core technology competencies in high growth markets, which will strengthen our market leadership position in our growth platforms and create greater shareholder value when the economy begins to recover.”
