About this technology
Overview
A new class of polyimides, synthesized by Langley Research Center, has been evaluated by the Getty Conservation Institute's Materials Science Group for possible art conservation applications. Polyimides are noted for resistance to high temperature, wear and radiation. They are thermally stable and soluble in some common solvents. After testing under simulated exposures for changes in color, permeability and flexibility, one coating, ODPA-3, 3-ODA may be used to protect bronze statues from corrosion. A test on stained glass windows was unsuccessful.
