It is now possible to economically produce, in series production, automotive glazing that has complex small radii feature lines (30). Such feature lines (30) are desirable as they can improve the stiffness of the glazing as well as contribute to the overall aesthetic and differentiation of the vehicle, allowing body lines to blend into and continue in the glazing. However, traditional automotive laminating methods do not lend themselves well to this type of product. Typically, the offset between the mating surfaces of the laminate must be very uniform. Such uniformity is difficult to achieve when producing small radii features. Rather than bending multiple layers with small radii feature lines that can be nested and subsequently laminated using standard plastic automotive interlayers, the invention makes use of a two part method for laminating, a dry lamination process and a wet lamination process, which requires only that the feature lines (30) be present in the outer glass layer (201).

A light transmissive substrate having a coating is disclosed. The coating is formed of an adhesion promoter that includes a metal, a metal oxide, or a metal nitride. A laminate including a coated substrate is also disclosed. A method of coating a substrate is further disclosed.

Methods of manufacturing electrochromic windows are described. Insulated glass units (IGU's) are protected, e.g. during handling and shipping, by a protective bumper. The bumper can be custom made using IGU dimension data received from the IGU fabrication tool. The bumper may be made of environmentally friendly materials. Laser isolation configurations and related methods of patterning and/or configuring an electrochromic device on a substrate are described. Edge deletion is used to ensure a good seal between spacer and glass in an IGU and thus better protection of an electrochromic device sealed in the IGU. Configurations for protecting the electrochromic device edge in the primary seal and maximizing viewable area in an electrochromic pane of an IGU are also described.

A process for the manufacture of a colored laminated glazing including at least two glass sheets connected together by a thermoplastic interlayer, includes deposition, by the liquid route, on a first glass sheet, of a polymeric layer including a coloring agent and polymeric compounds, drying and optionally curing of the polymeric layer, assembling of the glass sheet, coated with the colored polymeric layer, with a colorless transparent thermoplastic interlayer and with the second glass sheet, so that the colored polymeric layer is in direct contact with the interlayer, degassing, during which the air trapped between the glass sheets and the thermoplastic interlayer is removed, and heat treatment under pressure and/or under vacuum of the laminated glass at a temperature of between 60 and 200° C., during which the coloring agent present in the polymeric layer migrates toward the thermoplastic interlayer and during which the laminated glazing is assembled.

A ballistic glass assembly including a first glass layer and a second layer including a polyethylene terephthalate (PET) adhesive film. The ballistic glass assembly may also include an intermediate layer comprising a substantially transparent impact resistant material positioned between the first layer and the second layer. Methods of forming the ballistic glass assembly where the second layer and the intermediate layer match the contour of the first glass layer.

Techniques for laser processing of a workpiece including electrochromic glass or other thin-film devices where one or more layers are sandwiched between two thin-film conductive layers include directing a laser beam from a laser source onto a surface of the workpiece, wherein the laser beam comprises projected light, the projected light having a selected near-infrared wavelength in the range of about 1.4 to about 3 μm. Where the workpiece comprises an electrochromic device including an electrochromic stack disposed between a first transparent conductive layer, distal from the laser source, and a second transparent conductive layer, proximal to the laser source, removing the material includes removing a portion of the second transparent conductive layer and a portion of the electrochromic stack to expose a surface of the first transparent conductive layer without damaging the first transparent conductive layer.

Methods of manufacturing electrochromic windows are described. An electrochromic device is fabricated to substantially cover a glass sheet, for example float glass, and a cutting pattern is defined based on one or more low-defectivity areas in the device from which one or more electrochromic panes are cut. Laser scribes and/or bus bars may be added prior to cutting the panes or after. Edge deletion can also be performed prior to or after cutting the electrochromic panes from the glass sheet. Insulated glass units (IGUs) are fabricated from the electrochromic panes and optionally one or more of the panes of the IGU are strengthened.

Provided is a glass-glass laminate. The glass-glass laminate includes a lower glass layer, an adhesive layer on the lower glass layer, an upper glass layer on the adhesive layer, and a decoration layer between the lower glass layer and the adhesive layer or between the upper glass layer and the adhesive layer, in which the adhesive layer includes a room-temperature adhesive material.

A glass sheet composite includes a first glass sheet, a second sheet disposed opposite the first glass sheet, and a liquid layer formed by sealing up a liquid between the first glass sheet and the second sheet, in which the glass sheet composite has a plurality of vibration areas that are independent of each other in a plan view. The glass sheet composite is a diaphragm including at least one vibrator disposed on one side or both sides of the glass sheet composite. The glass sheet composite enables independent vibration at each of the vibration areas, and enables not only stereophonic or multiphonic reproduction but also local reproduction to be performed along with images. Since the diaphragm includes a vibrator, this diaphragm is excellent in sound reproduction.

A viscoelastic plastic interlayer intended to be arranged between two glass sheets of a glazing in order to provide it with vibroacoustic damping properties, includes two outer layers of thermoplastic adhesive, an inner layer arranged between the two outer layers, the inner layer having a loss factor tan δ greater than or equal to 1.6 at 20° C. and for a frequency range of between 2 kHz and 8 kHz, and first and second barrier layers arranged respectively between the outer layers and the inner layer 3, and composed of a viscoelastic plastic material.
