Patina is designed for use on copper, brass, bronze, and our metal alloy metallic coatings. Patina reactions produce all of the various shades of blue & blue/greens that are so familiar with aged copper, brass, and bronze. This solution can be applied directly onto metal alloys, or onto the final, tacky coat of one of our metallic coatings. On metal alloys, Patina will react to form shades of purple, blue, and turquoise blue/green. When applied to one of our metallic coatings, the colors are determined by the coating being used, though they tend toward a variety of blues and greens. Regardless of the medium being used, colors may be altered with water mists or by subjecting the parts to high humidity for various periods of time.
By patina oxidizer, we mean any solution that will chemically oxidize or patina copper and it's alloys. This usually results in shades of blue, green, blue/green, but may include milky white, purples and others. A full sized reference work would be required in order to cover all of the known methods of patination of copper, brass and bronze. Some of the most common forms of application include immersion, spraying, splattering, brushing, dripping, or sponging the patina solution onto the part being colored. After a patina has formed, the color may be altered by with water or by applying another patina oxidizer solution over it.
Because there are so many different alloys of copper, and the application methods and uses of the patina oxidizers are so diverse, it is difficult to say with any certainty what colors will be produced by which patina oxidizer. Ranked in order of their strength, Patina, Verde Green and Aqua Blue work best on copper and copper alloys and our metallic coatings. These usually develop into light blues all the way to dark blue-greens, with patina the darkest and Aqua Blue the lightest. All of these oxidizers may be mixed together to form custom blends for your individual uses.
Application on Metallic Coatings
All five of these oxidizers can be used on top of our metallic coatings to produce patina effects. Once again, you may uses any method that allows the patina oxidizer to come into contact with the metallic coating. As a general rule, the patina oxidizer is applied to the metallic coating on top of the final coat of coating, while that final coat is still damp.

As with all chemicals, wear protective clothing, latex gloves,
eye protection and avoid breathing mist. Use adequate ventilation with a
chemical respirator when spraying. No known shelf life.
