Abstract

Die Erfindung schlägt eine Widerstandspaste vor aus einem polymeren Bindemittel und einem glasartigen Kohlenstoff als elektrisch leitendes Pigment. Eine mit der erfindungsgemäßen Widerstandspaste erzeugte Widerstandsschicht zeichnet sich aus durch hohe Abriebbeständigkeit und durch verbesserte Stabilität gegenüber Umgebungseinflüssen.
