Exhibit 99.3

On October 7, 2011, Jeffry N. Quinn, Chairman, President and Chief Executive Officer of Solutia Inc. (“Solutia”), sent the following e-mail correspondence to Solutia’s employees.

* * * * *

I have shared with you Solutia’s plans to grow through strategic, bolt-on acquisitions that expand our capabilities and increase the scale of our existing businesses. Since the beginning of 2010, we have made investments in innovative, premium products, expanded into emerging markets, and bolstered our existing operations through acquisitions and organic growth.

This growth strategy has led to record earnings, and we’ve continued to elevate Solutia’s position as a global leader in performance materials and specialty chemicals. In line with this goal and our stated strategy, I am proud to announce the acquisition of Southwall Technologies Inc., a leading innovator of energy-saving films and glass products for automotive and architectural markets.

Solutia has agreed to acquire Southwall for the purchase price of $113 million, and we expect to close the transaction by the first quarter of 2012. The acquisition will be funded from existing cash on hand and will not require additional third-party financing.

Southwall Technologies has been a leader in vacuum sputtering technology for more than 25 years, focused primarily on the window and window film markets. This acquisition will combine our expertise in process, design and product development with Southwall’s one-of-a-kind assets and proprietary capabilities, positioning Solutia as the global technology and manufacturing leader of high -tech and premium films.

If we look deeper look into the drivers of the acquisition, the value becomes apparent:

• This acquisition secures Solutia’s access to Southwall’s proprietary XIR technology, a key base material for Solutia’s high-growth V-Kool premium aftermarket window films.

• It brings added state-of-the-art manufacturing capacity and proprietary capabilities that will support the fast growing demand for high-tech films for the electronics market, an essential component in many e-readers, touch screens and smartphones.

• It gives Solutia the unique ability to expand its product offerings to our current customers by offering Southwall’s XIR transparent film encapsulated between layers of Solutia’s Saflex® polyvinyl butyral interlayers, creating an “interlayer stack” that forms a protective barrier against the harmful effects of the sun in laminated automotive glass, with some play in the architectural market.

• It positions Solutia as the global leader of sputtering technology with assets on three continents – Europe, North America and Asia. Southwall currently has 145 employees across four manufacturing locations – Germany, California, Wisconsin and Illinois.

• The combination of unmatched innovation, industry expertise and proprietary capabilities will allow Solutia to bring the next generation of premium XIR films to our customers and drive the development of conductive films that achieve more optimal levels of optical clarity and readability, positioning us to capture growth in high-tech electronics and sophisticated window film markets.

I am confident that Southwall’s manufacturing facilities, proprietary technologies and innovative products, combined with Solutia’s global capabilities and diverse market scope, will lead to lead to breakthrough technologies in the market and position Solutia to continue its ascension as the global leader in performance materials and specialty chemicals. I am very excited about adding Southwall to our team, and look forward to welcoming the business and its employees into the Solutia family.

Sincerely,

Jeff Quinn

Chairman, President and Chief Executive Officer
