Abstract: The invention relates to the use of a coating comprising at least one fatty-acid modified resin as an anti-fingerprint coating on a least one face of a glass sheet. In particular, the invention allows to provide an anti-fingerprint solution to be used for a glass sheet, which does not significantly affect the surface properties and the aesthetics of the coated glass compared to the naked glass. Moreover, the invention allows to provide an anti-fingerprint solution to be used for a glass sheet, which is sustainable in time and/or wearing of the surface.

Abstract: The invention relates to a method for producing magnetically induced patterns in a layer deposited on a glass sheet, said method comprising the following steps in succession, as said glass sheet runs over a horizontal roller conveyor in a direction perpendicular to the largest dimension of the rollers of said roller conveyor: (i) depositing, in the form of a layer, a liquid composition on that face of the glass sheet which is opposite the face resting on the conveyor, the composition comprising magnetically orientable particles; (ii) selectively exposing the glass sheet comprising the layer of liquid composition to a magnetic field; and (iii) hardening the liquid composition. According to the invention, the step of selective exposure to a magnetic field is carried out by means of at least one roller of the conveyor comprising at least one element made of a permanently magnetic material integrated into its surface, so as to produce magnetic field lines in a region of the sheet running over the conveyor.

Abstract: The invention relates to a glass sheet having an enamel-based coating provided on at least one of its surface, which is in direct contact with said sheet and which comprises: a glass frit, inorganic pigments and organic compounds comprising at least one cross-linked compound, said coating exhibiting a xylene resistance of at least 00double rubs, as measured using the Solvent Resistance Rub Test according to ASTM D5402-06 (2011) as modified therein. Such a glass sheet can be heat treated (for example, in view of a subsequent tempering process) and, before heat treatment, can be handled and transported without damaging the coating, can be cut and ground without causing the coating to peel off or to be damaged at the borders of the cutting line, and offer a good resistance under running water, avoiding the peeling off or destruction of the coating during edges grinding or storage or transportation.

Abstract: Glass sheets according to the invention, in particular lacquered glass sheets, are covered with a coating of enamel. This coating comprises between 11 and 40% of organic material. Such glass sheets may be heat treated and, before heat treatment, may be handled and transported without damaging the coating, may be cut and ground without causing the coating to peel off or to be damaged at the borders of the cutting line, and offer a good resistance under running water, avoiding the peeling off or destruction of the coating during edges grinding or storage or transportation.

Abstract: The invention relates to an article made of coated glass, in particular an article comprising a glass sheet covered with an enamel coating. The glass article of the invention is resistant transport and handling, can be used in a twin application and can be tempered, i.e. can be heat-treated with a view to later tempering same. Specifically, the article of the invention includes: (i) at least one glass sheet; (ii) an enamel coating on at least one of the surfaces of the glass sheet; and (iii) at least one wax provided in and/or on said enamel coating.

Abstract: The present invention relates to a method for heating glass sheets having an organic material-based coating in an oven, particularly with a view to the subsequent tempering thereof. More precisely, the invention relates to a method enabling glass sheets having an organic material-based coating to be heat treated by enabling the management of the rapid and violent combustion of said organic material in the oven, using a forced heat convection effect due to a hot gas comprising an oxidizer, injected above the glass sheet at least between t1 and t2, t1 being the time at which the flames from the combustion of the organic matter appear and t2 the time when said flames disappear.

Abstract: The present invention discloses a method for treating at least a portion of at least one surface of a glass article which comprises the following steps, whatever their order: dry application of at least one high-pH solid material on said portion; heating of said glass article to a temperature at least equal to the melting temperature of the said high-pH solid.

Abstract: The present invention discloses a method for treating at least a portion of a surface of a glass article which comprises the following steps, whatever their order: application of a water solution comprising at least one high-pH solid material on said portion of the glass article; heating of said glass article to a temperature at least equal to the evaporation temperature of water.
