<p>The invention relates to a method for connecting a first joining partner (1) to a second joining partner (2). After provision of the first joining partner (1) and the second joining partner (2), a lacquer layer (11) is applied to the first joining partner (1). Then the first joining partner (1) and the second joining partner (2) are saturated together with an impregnating resin (8). The lacquer layer (11) is produced from a lacquer composition based on an epoxy resin mixture, a curing accelerator, a silane-based, epoxy-functional bonding agent, and a solvent. The epoxy resin mixture has 10 wt.-% to 94 wt.-% of at least one solid epoxy resin with a maximum epoxy count of 2 Eg/kg, 1 wt.-% to 50 wt.-% of at least one solid, multifunctional epoxy resin with an epoxy count > 4 Eg/kg, and 5 wt.-% to 40 wt.-% of a phenol and/or kresol novolak with a melting point > 30°C. After impregnation, the viscosity of the impregnating resin (8) is reduced such that the first joining partner (1) and the second joining partner (2) are connected to one another.</p> |
