Google Patents US6176905B1 - Process and reaction solution for producing a patina These roofings are also distinguished by their longevity and quality.US6176905B1 - Process and reaction solution for producing a patina Aluminum roofing materials painted in natural patina color is the best alternative to natural copper. In addition, we are able to offer alternative material for architects and property owners who love patina color. Patina is a material for the aesthetic appearance of the projected building. Over the years, the roofs have changed their color to green, as the copper roof was erected on buildings erected in Germany and other European countries.Thanks to the technology we offer, there is no need to wait for many years to paint copper naturally with different colors. Although the copper is golden at the initial stage, several days after the installation, the atmosphere changes it into a dark brown color. After 3-5 years on the seafront and 8-12 years in the continental climate, it is completely transformed into green-colored patina.
Thus, the German people who value the quality have emphasized the fact that they have only copper roofing on the buildings for centuries. This material is never corrosive. At the same time, the roof that covers with the copper gives to the building special beauty.
Because copper material is the best quality and reliable material for roofing and facade systems. For the German people, who attach special importance to quality in every field, this is not accidental. In Europe, especially in Germany, copper material is especially important for roofing materials. In more historic buildings in Europe, you can see such roofings. If the design of the building expresses energy and strength, TECU Patina is the right choice.
