Abstract: A coil and an electrical strip or electrical sheet with at least one heat-hardening hotmelt varnish, namely a baked enamel layer, provided on its flat sides, which has an epoxy resin base, at least one hardener, and at least one filler, are disclosed. In order to achieve a high storage stability and long-term temperature stability, the proposal is made for the filler of the baked enamel layer to have a metal carbonate, sulfate, sulfide, silicate, or phosphate or any mix of a plurality of these.

Abstract: A laminated core and a method for connecting sheet metal parts to form a laminated core, wherein sheet metal parts are separated from a sheet metal strip having, at least in some regions, a layer of curable polymer adhesive, and the sheet metal parts with adhesive-coated sides facing one another are provided above one another and are bonded under pressure to form a laminated core. In order to create advantageous method conditions, according to the invention a mixture comprising water and a thermoplastic and/or cross-linkable adhesion promoter is provided on at least one of the adhesive layers facing one another during bonding of the sheet metal parts.

Abstract translation: 叠片芯和用于连接金属片部分以形成层压芯的方法，其中将金属片与至少在一些区域中至少有一些可固化聚合物粘合剂的片状金属带分开，并且具有粘合剂的金属片部分 彼此面对的涂覆侧彼此相对地设置并且在压力下结合以形成层压芯。 为了产生有利的方法条件，根据本发明，在金属片部分的接合期间，在至少一个彼此面对的粘合剂层之间提供包含水和热塑性和/或可交联粘合促进剂的混合物。
