  • Patent number: 9125247
    Abstract: A plastic window including a transparent plastic substrate having first and second sides. Bonded to the first side of the substrate is a plastic film, the film being thinner than the substrate. An electrically conductive grid, including at least one conductive connector location, is encapsulated between the substrate and the film. Extending into the substrate, at least one electrical connector is positioned in electrical contact with the conductive mounting so that an electrical voltage supply can be connected to the conductive mounting and an electrical current can be caused to flow through the conductive grid.

  • Publication number: 20080280503
    Abstract: A plastic panel system including a transparent plastic panel and an electrically conductive grid. The panel includes a substrate and the grid is provided on the panel so as to overlie the substrate. Including with the grid is at least one conductive mounting location. An electrical connector, which includes a plastic portion and an electrically conductive portion, is secured to the panel by ultrasonically welding the plastic portion to the panel. As a result of the retention of the connector with the panel, the conductive portion of the panel is in electrical contact with the mounting location of the conductive grid. The electrical system of an automotive vehicle can be attached to the connector of the panel system.

  • Publication number: 20080280060
    Abstract: A process for flow, dip, or curtain coating a plastic panel with a weather resistant coating system of relatively uniform thickness is presented. More specifically, the process includes the step of rotating the plastic panel by about 180 degrees between the application of subsequent coating layers in order to minimize the variation in thickness measured near the top and bottom of the coated panel. The coatings are applied to the plastic panel at a predetermined coating angle (?).
