Polymeric glazings
The study presented was undertaken to evaluate polymer-coated silver mirrors with reflectances greater than 90% that can approach a lifespan of five years. Evaluation of silver mirrors has been initiated and is continuing, using realtime outdoor screening tests along with accelerated weathering devices. Mechanistic studies of degradation processes are also in progress. The experimental approach is multifaceted. Metallized films currently available from industrial sources are tested, commercially available polymeric films are silvered and tested, and polymeric films are formed onto silver films, which are deposited on a glass substrate for testing. A series of experiments demonstrates that the dimunition of reflectance using wet-processed silver is not a chemical effect. PMMA is found to be stable in sunlight. (LEW)
