Title (EN) WATER-DILUTABLE SOL-GEL COMPOSITION
(FR) COMPOSITION SOL-GEL DILUABLE AVEC DE L’EAU
Abstract: front page image
(EN)The present invention provides a sol-gel composition which is dilutable with water in any proportion and is based on the reaction of at least the following components: (i) a glycidyloxypropylalkoxysilane, (ii) an aqueous silica sol having a solids content of > 1% by weight, (iii)an organic acid as hydrolysis catalyst, and (iv) n-propyl zirconate, butyl titanate or titanium acetylacetonate as crosslinker, starting from a mass ratio of the solids mass of component (ii) to component (i) 0.75, a process for preparing it and its use, in particular as a sol-gel composition for corrosion control coatings, a corresponding corrosion control coat or primer coat, and articles equipped with such a coating.
(FR)La présente invention concerne une composition sol-gel qui est diluable avec de l'eau dans n'importe quelle proportion et est basée sur la réaction des composants suivants ou plus : (i) un glycidyloxypropylalcoxysilane, (ii) une solution de silice aqueuse ayant une teneur en solides supérieure à 1 % en poids, (iii) un acide organique en tant que catalyseur d'hydrolyse et (iv) le zirconate de n-propyle, le titanate de butyle ou l’acétylacétonate de titane en tant qu’agent de réticulation, à partir d'un rapport en masse de la masse de solides du composant (ii) sur le composant (i) valant 0,75, son procédé de préparation et son utilisation, en particulier en tant que composition sol-gel pour des revêtements anticorrosion, un revêtement ou revêtement primaire anticorrosion correspondant et des articles pourvus d’un tel revêtement.
