Abstract: Provided is a method for forming a coating containing an organic acid in a glass sheet production line while controlling an increase in the haze ratio of the glass. The method of the present invention is a method for producing a coated glass sheet, the method including the steps of cutting a glass ribbon to form a plurality of glass sheets in a glass sheet production line; and applying a solution onto the glass ribbon or the plurality of glass sheets in the glass sheet production line, the solution containing an organic acid and at least one selected from a water-soluble polymer and a polyphosphoric acid salt. The water-soluble polymer is preferably a water-soluble high-molecular-weight polymer, and more preferably a water-soluble copolymer. A preferred water-soluble copolymer contains a vinylpyrrolidone unit.

Abstract: A process for the production of an optoelectronic device, such as a photovoltaic cell or a light emitting diode is disclosed. The process comprises providing a substrate having a conductive coating on at least one surface, the conductive coating having an initial roughness and at least one or more spikes, and applying a functional component to the coated surface of the substrate. The surface of the substrate having the conductive coating has been subjected to a polishing step using at least one brush to reduce the height of the spikes inherent to the conductive coating and to give the conductive coating a final roughness. By reducing the spikes there is less potential for the optoelectronic device to suffer from electrical shunts which reduce the efficiency of the device.

Abstract: A method of improving the stain resistance of a surface of a glass article such as a float glass ribbon or float glass sheet is disclosed. The method comprises the steps of (i) applying a solution comprising a stain inhibitor to an absorbent strip; (ii) transferring solution from the wet strip to the surface of the glass article; and (iii) drying the wet glass surface to leave stain inhibitor on the surface of the glass article. A facility for manufacturing the glass article incorporating an apparatus for applying a solution comprising a stain inhibitor to the surface of the glass article in accordance with the aforementioned method is also disclosed.

Abstract: A stain inhibitor, which acts to neutralise alkali leached to the surface of a sheet of glass in the presence of water is disclosed. The stain inhibitor comprises a buffered, non-acidic compound, with a pKa value of between 6.0 and 10. Preferably, the non-acidic buffer compound is a mixture of boric acid and borax.

Abstract: An intrusion resistant laminated glazing, suitable for automotive use, comprises an impact resistant ply of rigid thermoplastic polyurethane sensitive to ultra-violet radiation and, outside said ply, an ultra-violet absorbing or reflecting ply. The ultra-violet absorbing ply may be of thermoplastic polyurethane interlayer material which serves to bond the rigid thermoplastic polyurethane ply to outer glass plies. By using interlayer materials of low modulus to bond the rigid thermoplastic ply to outer glass plies, a product with good impact resistance and intrusion resistance is achieved.
