Abstract: As car manufacturers have worked to improve the fuel efficiency of their vehicles, one of the areas where they have been able to make major improvements has been aerodynamics. As most of the drag is the result of the frontal area of the vehicle, the installation angle of the windshield has been getting smaller and smaller to facilitate the smooth displacement of air. One of the drawbacks of this approach is that the light reflected back to the driver by the windshield increases as the installation angle decreases and the incidence angle increases. At high incidence angles, the intensity of the reflection may become objectionable. The invention reduces reflection at high incident angles by means of an anti-reflective layer and a polarization layer.

Further, the coating is suitable for use over the entire area of the windshield, has excellent solar control properties and has a low sheet resistance allowing it to be electrically defrosted at common automotive voltages.

Abstract: Due to the increased glazed area of modern vehicles, especially the large panoramic glass roofs, we have seen a substantial growth in the use of anti-reflective coatings. Unfortunately, these types of coatings accentuate fingerprints and smudges. The invention provides an automotive glazing which is substantially resistant to fingerprints, and a method of manufacture thereof through the application of an anti-fingerprint coating based on low surface energy silanes.

Abstract: Due to the increased glazed area of modern vehicles, especially the large panoramic glass roofs, we have seen a substantial growth in the use solar control glass and coatings. The solar glass compositions and coatings are expensive to manufacture. While solar coatings are more efficient than compositions, they typically cannot be used on monolithic glazing as they are not durable. They must be applied to one of the surfaces on the inside of a laminate. Most of these products also introduce an undesirable color shift. The invention provides a coating that can be used on glass to produce a laminated or monolithic glazing with a neutral gray solar control coating which also has anti-reflective properties and low emissivity.
