Title (DE) VERFAHREN ZUR BESCHICHTUNG VON METALLISCHEN OBERFLÄCHEN MIT EINER SILAN-REICHEN ZUSAMMENSETZUNG
(EN) METHOD FOR COATING METALLIC SURFACES WITH A SILANE-RICH COMPOSITION
(FR) PROCEDE DE REVETEMENT DE SURFACES METALLIQUES AU MOYEN D'UNE COMPOSITION RICHE EN SILANE
Abstract:
(DE) Die Erfindung betrifft ein Verfahren zur Beschichtung einer metallischen Ober-fläche mit einer wässerigen Zusammensetzung zur Vorbehandlung vor einer weiteren Beschichtung oder zur Behandlung, bei der die Zusammen-setzung neben Wasser a) mindestens ein hydrolisierbares oder zumindest teilweise hydrolysier- tes Silan, b) mindestens ein Metallchelat und ggf. auch c) mindestens einen organischen Filmbildner, d) mindestens einem langkettigen Alkohol als Filmbildungshilfsmittel oder/und e) mindestens eine anorganische Verbindung in Partikelform enthält, wobei die saubere, gebeizte, gereinigte oder/und vorbehandelte metallische Oberfläche mit der wässerigen Zusammensetzung in Kontakt gebracht und ein Film auf der metallischen Oberfläche ausgebildet wird, der anschließend getrocknet wird, teilweise oder gänzlich durch Verfilmen verdichtet wird, und ggf. zusätzlich ausgehärtet wird, wobei der getrocknete und ggf. auch aus-gehärtete Film eine Schichtdicke im Bereich von 0,01 bis 10 µm aufweist. Ferner betrifft die Erfindung entsprechende wässerige Zusammensetzungen.
(EN) The invention relates to a method for coating a metallic surface with an aqueous composition for pretreating before applying another coating or for treating said metallic surface. In addition to water, the composition contains: a) at least one hydrolyzable or at least partially hydrolyzed silane; b) at least one metal chelate, if necessary, also; c) at least one organic film former; d) at least one long-chain alcohol that serves as a film forming aid and/or; e) at least one inorganic compound in particle form. The unsoiled, scoured, cleaned and/or pretreated metallic surface is brought into contact with the aqueous composition and a film is formed on the metallic surface, is subsequently dried, compacted in part or completely by film formation and, if necessary, additionally hardened. The dried and, if necessary, additionally hardened film has a layer thickness ranging from 0.01 to 10 µm. The invention also relates to corresponding aqueous compositions.
(FR) L'invention concerne un procédé de revêtement d'une surface métallique au moyen d'une composition aqueuse destinée au traitement préalable avant revêtement ultérieur, ou au traitement. Ladite composition contient, en plus de l'eau, a) au moins un silane hydrolysable ou au moins partiellement hydrolysé ; b) au moins un chélate de métal ; c) au moins un agent filmogène organique ; d) au moins un alcool à chaîne longue servant d'auxiliaire filmogène ; et/ou, e) au moins un composé anorganique sous forme particulaire. Selon ledit procédé, la surface métallique propre, décapée, lavée et/ou prétraitée est mise en contact avec la composition aqueuse, et un film est formé sur la surface métallique, séché, condensé par pelliculage partiel ou intégral, et éventuellement durci, ledit film séché et éventuellement durci présentant une épaisseur de couche de 0,01 à 10 µm. L'invention concerne également des compositions aqueuses correspondantes.
