For decades, scientists have recognized two unique effects of titanium dioxide, a common compound that is used in products as diverse as quick-setting concrete, tile grout and even suntan lotion. When exposed to sunlight, titanium dioxide acts as a catalyst to break down organic matter, while also creating a superhydrophilic (water-loving) surface.
Now, Alcoa Architectural Products has developed a proprietary, patent-pending process that leverages HYDROTECT™ technology from TOTO® to apply a titanium dioxide coating, called EcoClean™, to the pre-painted aluminum surface of Reynobond®. The result is the world’s first coil-coated aluminum architectural panel that helps clean itself and the air around it.
TOTO’s patented HYDROTECT™ technology protects our planet by drawing on sunlight, rainwater and other natural forces to help cleanse the global environment. Alcoa’s breakthrough was determining how to apply that technology to pre-painted metal – creating the EcoClean™ coating.
