Erfindungswesentlich ist, dass der Offenzeit-Verlängerer einen pKa Wert zwischen 4 und 14 hat und entweder eine Phenol- und/oder Chinon-basierte Verbindung oder ein Gemisch von Phenol- und/oder Chinon-basierten Verbindungen ist. Die Verwendung solcher Verbindungen, die bislang schwerpunktmäßig im Bereich der Polystyrolchemie angewendet wurden, in der Lackchemie ist überraschend.It is essential to the invention that the open time extender has a pKa value between 4 and 14 and is either a phenol and/or quinone-based compound or a mixture of phenol and/or quinone-based compounds. The use of such compounds, which have so far been used primarily in the field of polystyrene chemistry, in paint chemistry is surprising.
Bevorzugt ist diese Verbindung ein Stoff aus der Gruppe 2-tert-butylbenzene-1,4-diol, 4-MethoxyPhenol, 2-Methylhydrochinon, C-7-C9-verzweigtes Alkyl-[3-(3,5-di-tert-butyl-4-hydroxyphenyl)]propionat oder ein Gemisch von Stoffen aus dieser Gruppe; besonders bevorzugt sind 2-tert-butylbenzene-1,4-diol, 4-MethoxyPhenol.This compound is preferably a substance from the group 2-tert-butylbenzene-1,4-diol, 4-methoxyphenol, 2-methylhydroquinone, C-7-C9-branched alkyl-[3-(3,5-di-tert- butyl-4-hydroxyphenyl)]propionate or a mixture of substances from this group; Particularly preferred are 2-tert-butylbenzene-1,4-diol and 4-methoxyphenol.
Diese Stoffe, die insbesondere beispielsweise von der Firma Solvay erhältlich sind, haben eine gegenüber den aus dem Stand der Technik bekannten NH-basierten Offenzeitverlängerern Succinimide, 1 , 2 , 4 , -Triazole, 1, 2, 3, -Benzotriazole, 5, 5-Diphenylhydantoine, Hydantoine, (RS) -3-Ethyl-3-methylpyrrolidin-2 , 5-dion verbesserte Umwelt-, physiologischer und karzinogener Verträglichkeit.These substances, which are available in particular, for example, from Solvay, have a higher resistance to the NH-based open time extenders known from the prior art: succinimides, 1, 2, 4, -triazoles, 1, 2, 3, -benzotriazoles, 5, 5 -Diphenylhydantoins, hydantoins, (RS)-3-ethyl-3-methylpyrrolidine-2, 5-dione improved environmental, physiological and carcinogenic compatibility.
Ein weiterer großer Vorteil der erfindungsgemäßen Offenzeit-Verlängerer besteht darin, dass sie mit den Katalysatoren C gemeinsam in einer Katalysator-Komponente eines Beschichtunsgsystems enthalten sein können, die gegebenenfalls weiteren Lösungsmitteln und Topfzeit-Verlängerer enthalten kann, während die CH-acide Verbindung A und die vinylogen Carbonverbindungen B zusammen mit den eingesetzten Lichtschutzmittel und zumindest einem Teil der Topfzeitverlängerer in einer Bindemittelkomponente, die einen Stammlack bildet, zusammengefasst werden können. Dies ermöglicht dem Anwender eines solchen Beschichtungssystems die Nutzung einer identischen Stammlackkomponente bei verschiedenen Offenzeiten, die durch die Katalysator-Komponente gesteuert werden kann. Damit liegt es in der Hand des Anwenders, wie er bei einer gegebenen zu lackierenden Objektgeometrie die Offenzeit wählen möchte.Another major advantage of the open-time extenders according to the invention is that they can be contained together with the catalysts C in a catalyst component of a coating system, which can optionally contain further solvents and pot-life extenders, while the CH-acidic compound A and the vinylogenic carbon compounds B together with the light stabilizers used and at least some of the pot life extenders can be combined in a binder component that forms a base varnish. This allows the user of such a coating system to use an identical base paint component with different open times, which can be controlled by the catalyst component. This means it is up to the user how he wants to choose the open time for a given object geometry to be painted.
