Final Project Report G-Plus Windshield Coatings
Samples of Sungate windshield material provided by PPG were analyzed to ascertain failure mechanisms observed at the interface between a copper busbar and the electrically conductive coating in use. Samples of “failed” windshield material were characterized using optical and electron microscopy, as well as surface analysis methods. These were compared to corresponding samples of “good” coatings. The primary failure mechanism of the coated windshield appears to be related to electrical discharges that originate where air-filled gaps are present between the copper busbar and the conductive coating. Gaps are produced by irregularities or wrinkles in the copper busbar that may result from the installation process.
