electrically conducting varnishes: They have the function to provide
a nonconductive substrate with an electrically conducting layer. This
need depends on different technological requirements. A good exam-
ple is the application of conductive primers for plastics. They contain
conductive pigments, like carbon black or micas, coated with a tin/
antimony oxide layer, and are used to make possible the electrostaticcoating of non-conductive plastic work pieces.
electrochemical series: Classification system, mainly used for metals,
