1. An electrically conductive epoxy resin coating, comprising
at least one liquid epoxy resin selected from aromatic glycidyl ethers having an epoxy equivalent weight in the range from 110 to 200 g/mol,
at least one amine of the formula (I)
Z—NH-A-NH—CH2—Y  (I)
where
A is a divalent C2 to C15 alkylene, cycloalkylene or arylalkylene radical optionally containing one or more nitrogen atoms or ether groups, and
Z is H or —CH2—Y, and
Y is H or a C1 to C12 alkyl, cycloalkyl, arylalkyl or aryl radical,
where the amine of the formula (I) contains a total of at least 8 carbon atoms,
carbon nanotubes, and
at least one further constituents selected from the list consisting of further amines, accelerators, fillers, thinners, surface-active additives and stabilizers.
