Abstract
(DE)
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung wenigstens einer Beschichtung (B1) auf einem Substrat, welches wenigstens die Schritte (1) bis (5) umfasst, nämlich Bereitstellung einer Beschichtungsmittelzusammensetzung (BZ1) (1), Ermittlung der mittleren Filamentlänge der bei einer Rotationszerstäubung der gemäß Schritt (1) bereitgestellten Beschichtungsmittelzusammensetzung (BZ1) gebildeten Filamente (2), Reduzierung dieser ermittelten mittleren Filamentlänge (3), Aufbringen von wenigstens der nach Schritt (3) erhaltenen Beschichtungsmittelzusammensetzung (BZ1) mit reduzierter mittlerer Filamentlänge auf ein Substrat unter Bildung wenigstens eines Films (F1) (4) und physikalische Härtung, chemische Härtung und/oder Strahlenhärtung wenigstens des gemäß Schritt (4) auf dem Substrat gebildeten wenigstens einen Films (F1) zur Ausbildung der Beschichtung (B1) auf dem Substrat (5) sowie eine auf einem Substrat befindliche Beschichtung (B1), welche mittels dieses Verfahrens erhältlich ist.
(EN)
The invention relates to a method for producing at least one coating (B1) on a substrate, having at least the steps (1) to (5), namely providing a coating agent composition (BZ1) (1), ascertaining the average filament length of the filaments (2) formed during a rotational atomization of the coating agent composition (BZ1) provided in step (1), reducing the ascertained average filament length (3), applying at least the coating agent composition (BZ1) obtained in step (3) with a reduced average filament length onto a substrate, thereby forming at least one film (F1) (4), and physically curing, chemically curing, and/or radiation-curing at least the at least one film (F1) which is formed on the substrate in step (4) in order to form the coating (B1) on the substrate (5). The invention also relates to a coating (B1) which can be found on a substrate and which can be obtained using said method.
(FR)
La présente invention concerne un procédé de production d'au moins un revêtement (B1) sur un substrat, qui comprend au moins les étapes (1) à (5), à savoir (1) la préparation d'une composition de produit de revêtement (BZ1), (2) la détermination de la longueur moyenne des filaments formés lors d'une pulvérisation par rotation de composition de produit de revêtement (BZ1) préparée à l'étape (1), (3) la réduction de cette longueur moyenne des filaments déterminée, (4) l’application d'au moins la composition de produit de revêtement (BZ1), obtenue après l’étape (3), avec une longueur moyenne des filaments réduite sur un substrat en formant au moins un film (F1), et (5) le durcissement physique, le durcissement chimique et/ou le durcissement par rayonnement d’au moins ledit au moins un film (F1) formé à l'étape (4) sur le substrat aux fins de formation du revêtement (B1) sur le substrat, ainsi qu'un revêtement (B1) appliqué sur un substrat, pouvant être obtenu au moyen de ce procédé.
