A one-component thermosetting epoxy resin includes compositions that are particularly suitable for the bonding of substrates having different coefficients of thermal expansion, especially in the shell construction of modes of transport or white goods. The one-component thermosetting epoxy resin composition includes a) at least one epoxy resin A having an average of more than one epoxy group per molecule; b) at least one 2,4-diamino-1,3,5-triazine GU containing, in the 6 position, —an alkyl radical having 1 to 20 carbon atoms, in which one hydrogen atom in the α position has been replaced by a 2,4-diamino-1,3,5-triazin-6-yl radical, a cycloalkyl radical having 5 to 12 carbon atoms or -an aryl radical having 6 to 12 carbon atoms; and c) at least one toughness improver D, which is a terminally blocked polyurethane polymer D1. |
