This chapter presents the results of “a series of studies evaluating the protective efficiency of two newly developed coatings on artificially aged bronze.” The assessment was carried out on two bronze alloys representative of bronze used for outdoor monuments (traditional Cu-Sn-Zn-Pb patinated through accelerated aging and modern Cu-Si-Mn with artificial black patination), coated with two different eco-friendly, nonhazardous coatings (FA-MS on the patinated Cu-Sn-Zn-Pb and PropS-SH on the patinated Cu-Si-Mn). They were developed within the M-ERA.NET project, B-IMPACT (2015-2017) and are detailed hereafter. Based on a preliminary electrochemical testing campaign, using a reference commercial coating (INCRALAC) as the benchmark, the selection and development of protective coatings were followed by accelerated aging, through the reproduction of the leaching action of rainwater in outdoor conditions. The results allowed a deeper insight into the protective ability of the coatings investigated.

Abstract
This chapter presents the results of “a series of studies evaluating the protective efficiency of two newly developed coatings on artificially aged bronze.” The assessment was carried out on two bronze alloys representative of bronze used for outdoor monuments (traditional Cu-Sn-Zn-Pb patinated through accelerated aging and modern Cu-Si-Mn with artificial black patination), coated with two different eco-friendly, nonhazardous coatings (FA-MS on the patinated Cu-Sn-Zn-Pb and PropS-SH on the patinated Cu-Si-Mn). They were developed within the M-ERA.NET project, B-IMPACT (2015-2017) and are detailed hereafter. Based on a preliminary electrochemical testing campaign, using a reference commercial coating (INCRALAC) as the benchmark, the selection and development of protective coatings were followed by accelerated aging, through the reproduction of the leaching action of rainwater in outdoor conditions.
