[Download not found]The ultimate goal of this three-phase research project was to develop new coating strategies through an increase in understanding of how coatings for outdoor bronze sculpture and ornamentation work and fail. The immediate objective of Phases II and III of the project was to determine the weathering performance of five medium to high performance coating systems, previously tested in Phase I, on four typical bronze or copper-alloy substrates. The evaluation of these metal/coating systems, spread over the second two phases of the project, included chemical, physical, and electrochemical impedance methods after both accelerated and natural weathering. Overall failure ratings were compiled through visual evaluation of various properties according to appropriate ASTM standards, combined with digital analysis of corrosion after weathering. In this report, recommendations concerning protective coating options and practices as they relate to outdoor bronze sculpture and ornamentation are based on overall performance ratings and analytical results of Phase II samples.
