Subject: In principle the moisture can add reactive chemical species to the corona which can in principle change the chemistry of the treatment
In general it is best to use conditioned air for critical treatment applications but this is not what is generally done in practice. In principle the moisture can add reactive chemical species to the corona which can in principle change the chemistry of the treatment but this is difficult to define in terms of the chemical changes to the film surfaces. More often it causes other problems associated with condensation of gasses in the exhaust and cleanliness problems due to film contamination etc.
There are definite seasonal differences in how the treater can be run which most likely relate to both ambient temperature and moisture levels in the air, which can affect surface chemistry of the film. In general during summer I have observed a need to lower power settings due to film temperature and potential for blocking etc which diminishes or controls the tendency to over treat the film surface. This has resulted in seasonal changes in film properties which is where you should look to define if you have a moisture level problem.
