This invention is directed to methods of treating inorganic surfaces with aqueous compositions including ionic organosilicon compounds. Surprisingly, it has been found that the application of water soluble ionic organosilicon compounds, which until the present invention have only been used in small quantities to solubilize silanes, to inorganic surfaces provides the treated surface with an excellent hydrophobic property. The present invention exclusively utilizes ionic organosilicon compounds as the main or sole component for imparting water repellency upon surface treatment of inorganic substrates. The methods of the present invention comprise the application of ionic ogranosilicon compounds to inorganic surfaces whereby imparting water resistance to the substrate. After application, a treated surface may be characterized as having a long term water repellant property.
La présente invention concerne des procédés permettant de traiter des surfaces inorganiques avec des compositions aqueuses comprenant des organosiliciums ionisés. Il s'est avéré que l'application de d'organosilicium hydrosoluble ionisé, utilisé à présent à faible dose pour solubiliser les silanes, confère aux surfaces organiques ainsi traitées d'excellentes propriétés hydrophobes. La présente invention utilise exclusivement l'organosilicium ionisé comme unique ou principal composant pour conférer des propriétés hydrophobes lors de traitement de surface de substrats inorganiques. Les procédés de l'invention consistent en l'application d'organosilicium ionisé sur des surfaces inorganiques, ce qui permet de conférer au substrat de la résistance à l'eau. Après application, une surface traitée peut être caractérisée comme présentant une propriété hydrophobe de longue durée.
