Star Blue™
PREWEATHERED PATINA ON COPPER
Star Blue provides an aged copper look without the wait. It is available as a flat sheet good or for specification within a Zahner project.
Brooklyn, New York
While deep green copper patinas take over a century to develop naturally, Star Blue provides an expedited answer.
Zahner’s precisely controlled weathering process creates the desired blue-green antiquated appearance in days.
Once the Star Blue application has been carefully rolled onto the copper, the patinated metal may be installed on wall paneling systems, roofing systems, architectural accents, and sculpture projects of any scale.
With Star Blue, you’ll discover a range of colors and textures uncommon in the architectural metals community.
The patina will initially showcase the factory-produced color tone upon installation. But after a few months of exposure, Star Blue will evolve into a richer hue as it absorbs moisture from the air, carbon dioxide, and other pollutants.
This collaboration with natural elements creates a refreshing variability. The surface breaks from the uniform monotony often experienced on large buildings. The patina also provides a layer of natural protection for the copper alloy, making it a durable, long-lasting surface.
