  • Substrate with a photocatalytic coating based on titanium dioxide and organic dispersions based on titanium dioxide
    Patent number: 6362121
    Abstract: The invention relates to a substrate provided, on at least a portion of one of its faces, with a coating with a photocatalytic property based on titanium dioxide which is at least partially crystalline and which is incorporated in the said coating partly in the form of particles predominantly crystallized in the anatase form. The invention also relates to a process for the preparation of this substrate and organic dispersions of titanium dioxide particles used in the said process for the preparation of the substrate.

  • Substrate with improved hydrophilic or hydrophobic properties, comprising irregularities
    Patent number: 6299981
    Abstract: Substrate, at least part of at least one of the faces of which has a geometry which is optionally obtained by means of a coating and which differs from that of an ideal uniform, perfectly plane or even slightly curved, sheet, in that it has a bumps-and-hollows relief which can be defined by submicron sizes which, almost in their entirety, fall into at least two different classes, the respective representative values of which vary by a factor of at least 5 or of at most 1/5; applications of this substrate to anti-stain and anti-mist or anti-rain glazing; processes for preparing the substrate.

  • Compound for a non-wettable coating, process for treatment of glass with the aid of the compound and products obtained
    Patent number: 6258156
    Abstract: A composition for coating can be made by mixing a fluoroalkoxysilane containing an alkoxy moiety directly bonded to a silicon atom, an aqueous solvent system, and a catalyst. The composition can be used to form a hydrophobic and oleophobic layer on a substrate.
