Abstract
(DE)

Metalloberflächen müssen unter aggressiven Bedingungen gegen Korrosion geschützt werden. Die vorliegende Erfindung betrifft dazu ein Verfahren zur Herstellung organisch-anorganischer Schutzschichten auf metallischen Substraten. Hierzu wird eine Beschichtungszusammensetzung auf der Basis der Hydrolyse und Polykondensation geeigneter Silane und Phosphor- sowie Borverbindungen, ggf. in Anwesenheit nanoskaliger SiO2- oder B2O3-Partikel, erzeugt und auf die Metalloberfläche aufgebracht. Die Schichten werden getrocknet und thermisch verdichtet, wobei die Verdichtungstemperatur so niedrig ist, dass selbst Leichtmetalle damit beschichtet werden können. DOLLAR A Die resultierenden organisch-anorganischen transparenten Schichten bieten einen guten Korrosionsschutz, sind aber gleichzeitig auch thermisch stabil, kratzfest, abriebfest, hydrophob und schmutzabweisend.

(EN)

Protective organic-inorganic coatings are produced on metallic substrates by the hydrolysis and polycondensation of coating compositions containing (a) silanes with hydrolyzable groups or hydroxyl groups and optionally with non-hydrolyzable groups and (b) other compounds. - A method for the production of protective organic-inorganic coatings on metallic substrates involves using a coating composition based on the hydrolysis and polycondensation of silane(s) of formula RnSiX4-n (I) or their oligomers, plus one or more other compounds, in which - X = hydrolyzable groups or hydroxyl groups; - R = non-hydrolyzable groups; and - n = 0, 1 or 2.
