Although these differences can be seen right after installation, they soon become less noticeable on exposure to the elements. As a result of the manufacturing technology used, individual sheets can vary in colour from yellow green to blue green. The lively colour spectrum so typical of copper develops over time. Its colouring continually changes on exposure to the elements. TECU® Patina has similar properties to those of natural patina right from the start. “The most massive structure comes across as virtually weightless.” After installation, the surface develops in the completely natural manner characteristic of copper. Traces of processing remain practically invisible on the material surface, and even after folding and bending, the patina layer remains in good condition. The temporary yet robust transparent layer ensures long-lasting protection. New: TECU ® Patina now with TSP surface protection This gives the processed surfaces their excellent visual appearance. TECU® Patina surpasses the requirements of DIN EN 1172 with regard to tolerances and the most important technological values. Cu-DHP is outstandingly malleable, regardless of temperature and the direction of rolling. Cu-DHP is well suited for welding and soldering its degree of purity is at least 99.9 %, in accordance with DIN 1787 “Copper, Wrought Products”. They are made of Cu-DHP – oxygen-free, phosphorus-deoxidised copper with limited residual phosphorus.
TECU® Patina sheets are manufactured in state-of-the-art production facilities according to DIN EN 1172 and KME’s own strict guidelines. “Beautiful? Absolutely stunning! For how long? Forever!” The unique developments occurring in TECU ® Patina are exciting – just as modern architecture should be. The many different colour tones and shades eventually blend together, but only gradually. TECU ® Patina is always extremely varied, just as you would expect from a natural surface. This process causes an oxidised layer to form on the surface of the copper – a process similar to the natural patination that occurs over a long period of time when copper is exposed to atmospheric conditions. Using a specially developed industrial process, TECU ® copper sheets are patinated green on one side. The solution is TECU ® Patina – patinated copper for immediate use to satisfy the highest aesthetic demands in building design. When the design demands the power and expressiveness of the patina green typical for copper, then it should be implemented just as required – without waiting for the gradual changes caused by natural weathering. Often the shortest path takes you directly to your goal. Green copper for immediate creative application – all natural, no limits. „Pre-patinated copper for Roofing and Façade Cladding“
