Abstract
A process and panel for fixed automotive glazing, the panel molded from polycarbonate, a UV radiation blocking hard coat deposited thereon, and a pigmented primer applied in a defined band extending about the perimeter. The hard coat protects the pigmented primer coating so that two separate coatings are not required.
Claims7
A panel for use as a fixed glazing adhesively bonded about its perimeter to a body structure defining a window opening in an automotive vehicle, comprising a panel of clear molded polycarbonate;
- said panel having a UV radiation blocking hard coat deposited onto entire surface;
- a pigmented adhesive bond primer material applied over said hard coat in a band extending about a perimeter of said panel, said pigmentation producing an opaque black out of said band so that said primer material provides an adhesive joint masking band extending about said perimeter as well as being a bonding primer for strengthening said adhesive joint.
A panel for use as a fixed glazing adhesively bonded about its perimeter to a body structure defining a window opening in an automotive vehicle, comprising a panel of clear molded polycarbonate;
- a panel having a UV radiation blocking hard coat deposited onto entire surface;
- a pigmented adhesive bond primer material applied over said hard coat in a band extending about a perimeter of said panel, wherein said pigmented primer comprises a hydrocarbon ketone liquid with a carbon black pigment suspension.
A process for manufacturing a fixed automotive glazing panel adapted to be mounted in an opening in an automotive body structure by use of an adhesive bonded joint, comprising the steps of:
- molding a glazing panel from a synthetic resin;
- depositing a UV radiation-blocking hard coat onto the entire surface of said molded panel;
- applying a pigmented primer coating material onto the perimeter of an inside surface of said hard coated molded panel which is capable of bonding to the hard coat and to an adhesive sealant for mounting said glazing panel to said body structure, and provides a masking of the bonded joint between said glazing panel and said body structure.
