印刷行业中主要溶剂的表面化学特性

Using the contact angle measuing unit OCA20 with the SCA22 software and the pendant drop method results in a quick and easy way of 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.
