摘要:
An aqueous solution of a hydrophobic/oleophobic agent incorporating a primer of formula: X3SiRSiX3 (I) in which: R represents a carbon chain, and X represents a hydrolysable functional group.
摘要:
The invention relates to a composition for a hydrophobic/oleophobic coating containing at least one alkoxysilane and at least one halosilane, each having a perfluorinated group at at least one end of their molecule; it also relates to a process for forming a coating of this type on a substrate, as well as to this substrate itself when provided with its coating and, in particular, monolithic, laminated or multiple glazing at least in part provided with its coating.
摘要:
A window glass comprising a substrate made of glass, which is optionally covered, at least in part, by one or more layers and a hydrophobic-oleophobic, abrasion-resistant coating comprising an essentially mineral sublayer and a hydrophobic-oleophobic layer, wherein the density of the sublayer is equal to at least 80% of that of its constituent material.
摘要:
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.
摘要:
The subject of the invention is a transparent substrate, especially made of glass, provided on at least one of its faces with a layer based on an at least partially oxidized silicon derivative chosen from silicon dioxide or silicon oxides which are substoichiometric in terms of oxygen, silicon oxycarbide or silicon oxynitride, and having a hydrophilic character.
摘要:
The invention relates to a substrate (1) provided with a first coating (2) comprising at least one hydrophilic layer based on an at least partially oxidized silicon derivative, surmounted by a photocatalytic second coating (3) comprising partially crystallized titanium oxide and having a discontinuous/permeable structure. Application of this substrate to glazing, an architectural material or to mineral wool.
