Alcoa Architectural Products has released PrismFX color-shifting finishes, architectural coatings designed for Reynobond Aluminum Composite Materials and Reynolux profile materials, flat sheet and coil. The coating creates subtle color shifts as lighting conditions change throughout the day. A building that appears green, blue or silver in the morning can shift to copper, violet or gold in the afternoon. The coatings can withstand the corrosive effects of saltwater, UV exposure and extreme temperature shifts without warping, cracking or fading.
