Nach den Lehren des Hauptpatentes werden diese Überzugsmittel wie üblich in gepulverter Form auf die zu schützende Oberfläche, z.B. durch Aufstäuben oder elektrostatisches Aufspritzen aufgebracht und durch Erhitzen der Überzug erzeugt. Die Einbrenntemperaturen liegen zwischen 150 und 250 C, bevorzugt 180 bis 2000C, die Einbrennzeiten bei 10 bis 60 Min., vorzugsweise bei 20 bis 40 Min.According to the teachings of the main patent, these coating agents are applied as usual in powdered form to the surface to be protected, for example by dusting or electrostatic spraying, and the coating is produced by heating. The stoving temperatures are between 150 and 250 ° C., preferably 180 to 200 ° C., and the stoving times are 10 to 60 minutes, preferably 20 to 40 minutes.
In weiterer Ausbildung der Erfindung des Hauptpatentes wurde nunmehr gefunden, daß die gleichen in der Hitze härtbaren Überzugsmittel hervorragend zum Auftrag aus der Schmelze geeignet sind. Der Auftrag aus der Schmelze erfolgt lösungsmittelfrei bei Temperaturen zwischen 80 und 140 C, vorzugsweise zwischen 100 und 1200C nach den hierfür üblichen Methoden, insbesondere durch Walzen oder Rakeln. Anschließend werden die aufgetragenen Überzugsmittel bei Temperaturen oberhalb 1500C, wie im Hauptpatent beschrieben, zu harten, elastischenIn a further development of the invention of the main patent, it has now been found that the same heat-curable coating agents are outstandingly suitable for application from the melt. The application from the melt is solvent-free at temperatures between 80 and 140 ° C., preferably between 100 and 120 ° C., using the methods customary for this purpose, in particular by rolling or knife coating. The applied coating agents then become hard, elastic at temperatures above 150 ° C., as described in the main patent

und wetterfesten Überzügen ausgehärtet.and weatherproof coatings cured.
Die Arbeitsweise, Beschichtungen aus der Schmelze statt aus Lösungen in organischen Lösungsmitteln aufzubringen, ist unter Verwendung von thermoplastischen Kunststoffen bekannt. Ebenso gehören Schmelzkleber, d.h. Thermoplasten, die im geschmolzenen Zustand als Klebstoff aufgetragen werden, zum Stand der Technik. Eine Anwendung derartiger Thermoplasten zur Beschichtung von metallischen Untergründen anstelle einer Einbrennlackierung führt zu keinen harten und widerstandsfähigen Oberflächen, ihre Kratzempfindlichkeit ist zu groß, auch die Wetterbeständigkeit ist nicht im gewünschten Maße gegeben.The method of applying coatings from the melt instead of from solutions in organic solvents is below Use of thermoplastics known. Likewise, hot melt adhesives, i.e. thermoplastics that are in the melted State to be applied as an adhesive, to the state of the art. An application of such thermoplastics for the coating of metallic substrates instead of a stove-enamel finish do not lead to hard and resistant surfaces, their sensitivity to scratching is too great, and the weather resistance is also not given to the desired extent.
Bei dem Versuch, statt der Thermoplasten hitzeh'ärtende Bindemittel zu benutzen, wie sie in den Einbrennlacken für die industrielle Lackierung üblich sind, zeigt sich, daß sie lö- · sungsmittelfrei im Schmelzfluß bei den zur Anwendung gelangenden Temperaturen schon zum Teil nach Minuten gelieren. Außerdem liegt die Viskosität der Schmelze schon zu Anfang derart hoch, daß ein Auftrag durch Walzen oder Rakeln nicht möglich ist.When trying to use heat-curing binders instead of thermoplastics use, as they are customary in baking enamels for industrial painting, shows that they solve solvent-free in the melt flow for those used Temperatures can already gel in some minutes. In addition, the viscosity of the melt is so high at the beginning that a Application by rollers or squeegees is not possible.
Es war daher überraschend, daß die im Hauptpatent beschriebenen Pulverlacke derart hervorragend geeignete Mittel zur Schmelzbeschichtung darstellen.It was therefore surprising that the powder coatings described in the main patent were so outstandingly suitable agents for hot melt coating represent.
