charaterizing the netwoking properties of a liquid.
The upper surface tension is directly accessible and
the polar and dispersed components can easily be
calculated after determining the outer surface
tension compared with a non polar liquid.
In the case of the frequently used solvent DPM the previously
unknown polar and dispersed components of the upper
surface tension were established, knowledge of which
for many networking processes e.g.coatings is of
decisive impoutance.
