CA 2441004
The invention provides an anticorrosive surface coating composition comprising a resin system, and a hydrophobic metal oxide. The hydrophobic metal oxide is characterized by being produced via a wet process and having a surface area of at least about 350 m2/g. The invention also provides a method of producing such an anticorrosive coating composition. The invention further provides a substrate having a surface coated with the surface coating composition of the invention, as well as a method of imparting corrosion resistance to a surface of a substrate.
L'invention concerne une composition de revêtement de surface anticorrosif comportant un système de résine et un oxyde métallique hydrophobique. Ledit oxyde métallique hydrophobique se caractérise par le fait d'être produit au moyen d'un procédé par voie humide et possédant une zone de surface d'au moins 350 m?2¿/g environ. L'invention concerne également un procédé de production d'une telle composition de revêtement anticorrosif. L'invention concerne encore un substrat possédant une surface recouverte par la composition de revêtement de surface décrite par la présente invention ainsi qu'un procédé attribuant à une surface du substrat une résistance à la corrosion.
