Reynobond® with EcoClean™ Signals a New Milestone in
Environmentally Friendly Architectural Design

NEW YORK–Alcoa (NYSE: AA) today launched Reynobond® with EcoClean™,
the first coil-coated architectural panel that helps clean itself and
the air around it. This game-changing product was created by merging
breakthrough innovations in science and design from Alcoa and Japanese
manufacturer TOTO®.

Reynobond with EcoClean is an economically viable
self-cleaning technology that reduces maintenance costs and helps with
the decomposition of smog and other pollutants, from dirt to diesel
fumes, which cling to building surfaces. In fact, 10,000 square feet of
Reynobond with EcoClean has the approximate air cleansing power of 80
trees.

“Alcoa is committed to innovating sustainable solutions for today and
tomorrow,” said Craig Belnap, president, Alcoa Architectural Products.
“That passion is a driving force behind our architectural business. Our
R&D in science and technology is creating new ways for aluminum building
products to meet green building standards—from the use of natural
cleaning products like Reynobond with EcoClean, to advanced
façade solutions that help reduce CO2 emissions and energy consumption.”

Alcoa scientists developed a proprietary process that leverages patented
HYDROTECT™ technology from TOTO to apply a titanium dioxide coating,
called EcoClean, to the pre-painted aluminum surface of Reynobond. The
result is an aluminum panel that, when combined with sunlight, acts as a
catalyst to break down organic pollutants on its surface and in the air
around it, like smog, into harmless matter which is then washed away by
rainwater.

Last year, 80 billion square feet of commercial building space consumed
roughly 20 percent of all energy in the U.S. economy.1 Thanks
to strategic investments in R&D, Alcoa is fueling sustainable solutions
and mitigating environmental challenges facing the building and
construction industry by bringing Reynobond with EcoClean to
market. This represents an important step forward in sustainable
building design and will literally change the face – and façade – of the
industry.

Reynobond with EcoClean will debut at the AIA 2011 National
Convention and Design Exposition on May 12 in New Orleans.
