Experts
know: the quality of pretreatment is of
central importance to the quality of coating.
Consequently, already when cleaning and
processing the workpieces it all depends on
the application of the relevant optimized process.
Technically, but above all also with regard to the
protection of the products to be coated.
So, every stage of pretreatment involves an
individual reflection on various relevant factors.
Kind and level of contamination are two of them,
which are fundamental. Material, composition and
effect of the cleaning media are further ones.
Other parameters result from the interaction between
chemicals, mechanics, temperature and time, for example,
which not least have a decisive effect on the economic
efficiency of a pretreatment process.
