Alcoa Architectural Products has developed a proprietary process that leverages HYDROTECT™ technology from TOTO® to apply a titanium dioxide (TiO2) 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.

"Just as plants harness light for photosynthesis in nature, HYDROTECT nanotechnology does the same for manmade surfaces. An integrated part of the manufacturing process, HYDROTECT uses nontoxic titanium dioxide (TiO2) in the glazing and coating process." (see HYDROTECT brochure)
