Abstract

Einer Antidröhnmasse auf Epoxidharzbasis wird vor ihrer Verarbeitung ein Geliermittel zugesetzt. Dadurch geliert die Antidröhnmasse nach ihrer Applikation bereits im Rohbauofen bei Temperaturen von etwa 120° C und Verweilzeiten von 10 bis 12 Minuten in einem solchen Maße, dass sie der Beanspruchung in einer dem Lackiervorgang vorgeschalteten Vorbehandlung standzuhalten vermag. Das chemische Aushärten der Antidröhnmasse findet wie üblich nach der Lackierung in Öfen der Lackierstation statt.

Figure 00000001
An epoxy based antacid is added with a gelling agent prior to processing. As a result, the Antidröhnmasse gelled after its application already in the shell furnace at temperatures of about 120 ° C and residence times of 10 to 12 minutes to such an extent that it is able to withstand the stress in a pre-treatment preceding the painting process. The chemical hardening of the anti-damming mass takes place as usual after painting in ovens of the varnishing station.
