Abstract

Bei einem Verfahren zur Beschichtung von hochtemperaturbeständigen Oberflächen nach der Methode der Pulverbeschichtung mit Fluorthermoplasten, wird zunächst eine Grundschicht aufgetragen, die aus einem Fluorthermoplasten mit 15 bis 65 Vol.-% eingemischten Glaskugeln besteht, gefolgt von einer Deckschicht aus einem Fluorthermoplasten von gleichem Fließvermögen ohne Glaskugelzusatz. Auf diese Weise können Metalle und andere hochtemperaturbeständigen Oberflächen beschichtet werden, ohne daß es zum gravitationsbedingten Abfließen während des Beschichtungsvorganges kommt. In a process for coating high temperature resistant surfaces according to the method powder coating with fluorothermoplastics first applied a base layer consisting of a Fluorothermoplastics mixed with 15 to 65 vol .-% Glass balls consists of, followed by a top layer a fluorothermoplastic of the same fluidity without Glass ball additive. In this way, metals and other high temperature resistant surfaces coated become, without it flowing out due to gravity comes during the coating process.
