In 2002, researchers from North Dakota State University received funding from the NCPTT to study protective coatings for outdoor bronze sculpture and ornamentation. Previous research had shown that the most protective coatings tend to be impervious to conventional solvent removal techniques and that standard mechanical removal methods damage bronzes and their patinas. This study evaluates new solvent removable coatings and compares their protection to the currently used systems.

In 2001, North Dakota State University presented conclusions from the second year of a three year NCPTT funded project on outdoor bronze protective coatings. Coatings investigated include: a fluorocopolymer blended with various acrylics, conductive polymers, BTA pre-treatments, and a very fine titanium dioxide.

Some of the world’s most famous art will never appear in a gallery. Indeed, outdoor bronze sculpture may spend decades or centuries outdoors, exposed to pollution and extreme weather conditions. Researchers at North Dakota State University (NDSU) used a grant from NCPTT to study ways to test and develop a coating system to resist corrosion [...]
