Description

Die vorliegende Erfindung betrifft ein stark hydrophobierend wirkendes, mit Wasser verdünnbares Autoglanztrocknungsmittel, das in sehr verdünnter Form in Wasch- und Spülflüssigkeiten bei Autowaschanlagen verwendet wird. Bei der Autowäsche bildet sich durch die Anwendung von oberflächenaktiven Mitteln im Waschwasser auf der Fahrzeugoberfläche ein geschlossener, festhaftender Wasserfilm aus. Dieser Film muß entfernt werden, um die Bildung von Flecken oder Streifen durch die Salze und sonstigen Verunreinigungen des Wassers zu vermeiden. Zu diesem Zweck werden im Nachspülgang dem Wasser oberflächenaktive quaternäre Ammoniumverbindungen zugesetzt. Durch die Adsorption des kationischen Tensids an der Lackoberfläche reißt der Wasserfilm auf und das Wasser setzt sich in Form von Tropfen an der Lackoberfläche ab. Die Wassertropfen lassen sich dann leicht durch ein Gebläse entfernen.The present invention relates to a highly hydrophobic, with Water thinnable car gloss desiccant, which is in very diluted form is used in washing and rinsing liquids in car washes. In the Car wash is formed through the use of surface active agents in the Wash water on the vehicle surface a closed, adherent Water film off. This film must be removed to prevent staining or strips through the salts and other contaminants in the water avoid. For this purpose, the water in the rinse cycle surface-active quaternary ammonium compounds added. Through the Adsorption of the cationic surfactant on the paint surface tears the water film and the water settles on the surface of the paint in the form of drops. The water drops can then be easily removed by a blower.
