UGINOX Patina K44 is naturally resistant to corrosion and suitable for any environment.*
UGINOX Patina K44 will adapt to any location for roofs including coastal / marine areas and installed according to current good practices (e.g. NF DTU 40.44 French Code). When exposed to the atmosphere the Tin coating will develop a natural patina. In roofing applications the change is noticeable after a few weeks and especially following rainfall the process will be substantially complete after a few months.
In vertical cladding or sheltered soffits the surface receives less moisture and the patina will take longer to develop. In such areas, where cleaning operations may also be required we recommend an alternative Aperam facade surface such as UGINOX Top.
Behaviour to localised corrosion
Along with the tinned coating, the corrosion resistance of the underlying base material is of primary importance.
