Title
(DE) COIL UND ELEKTROBAND ODER -BLECH
(EN) COIL AND ELECTRIC STEEL STRIP OR SHEET
(FR) BOBINE ET BANDE OU TÔLE MAGNÉTIQUE
Abstract
(DE)
Es wird ein Coil und ein Elektroband oder -blech mit wenigstens einer auf einer dessen Flachseiten vorgesehenen, heißhärtenden Schmelzklebelackschicht, nämlich Backlackschicht, die eine Epoxydharzbasis, mindestens einen Härter und wenigstens einen Füllstoff aufweist, gezeigt. Um eine hohe Lagerstabilität und Dauertemperaturfestigkeit zu erreichen, wird vorgeschlagen, dass der Füllstoff der Backlackschicht ein Metallcarbonat, -sulfat, -sulfid, -silicat oder -phosphat oder eine beliebige Mischung mehrerer dieser aufweist.
(EN)
The invention relates to a coil and an electric steel strip or sheet comprising at least one heat-curing adhesive hot-melt enamel layer, specifically a baked enamel layer, which is provided on one of the flat sides thereof and has an epoxy resin base, at least one curing agent, and at least one filler. In order to obtain a high degree of storage stability and longterm heat resistance, it is suggested that the filler in the baked enamel layer comprises a metallic carbonate, sulfate, sulfide, silicate or phosphate or any mixture of a plurality of these.
(FR)
La présente invention concerne une bobine et une bande ou tôle magnétique, comportant sur une de leurs faces planes au moins une couche de vernis sous forme de colle fusible thermodurcissante, à savoir une couche de vernis thermoadhérent, qui comprend une base de résine époxyde, au moins un durcisseur et au moins une charge. Selon l'invention, pour obtenir une bonne stabilité au stockage et une résistance élevée aux hautes températures prolongées, la charge de la couche est un carbonate, sulfure, sulfate, silicate ou phosphate métallique ou un mélange quelconque de plusieurs de ces composés.
