To Do: Migrate


Coatings are often used to help protect bronzes from destructive erosion caused by outdoor weathering.   Experiments looking at improved coating systems for bronze were a focus of research at North Dakota State University. Previous research has shown that the most protective coatings tend to be impervious to conventional solvent removal techniques and standard mechanical removal methods may damage bronzes and their patinas.  This research focused on viable coatings that afford protection to the underling bronze surface while remaining removable under specific conditions not typically found in the outdoor environment.  The preparation and evaluation of various unconventional coatings for bronze was accomplished through synthesis and combinatorial methods.  The results of the initial testing of the new coating are included in this report.

This research was made possible through Grant MT-2210-03-NC-06 from the National Center for Preservation Technology and Training (NCPTT).
