7.2.1
Recommended cleaning agents
The paint supplier must provide cleaning agents tailored to the paint
system.
The cleaning agent should meet the following conditions:
- The cleaning agents used must not chemically dissolve the plastic
parts and covers of the application equipment.
- The physical and chemical properties of the materials in the
application technique that come into contact with the cleaning
agent may not change in any way.
- Dried paint material should dissolve well and be easily removable
(precleaning).
- The cleaning agent for non-flammable paints has to mix well with
water (final cleaning).
- The detergent must be completely removed without leaving any
residue or must evaporate in the available time (final cleaning).
You may preclean (pre-dissolve) dried paint residues that are difficult
to dissolve with a suitable cleaning agent on a conventional basis
even in non-flammable paints. Do that carefully with a rag soaked in
solvent. Pay utmost attention that the solvent does not change the
chemical and physical properties of the plastic parts and covers of the
application equipment.
Examples of critical ingredients
Ingredients with a pH value < 7 and pH > 7 (except water based
cleaning agents pH ~ 8 – 10) must not be used for cleaning.
The following table lists examples of critical ingredients that you
should never use in pure form (100%) as a cleaning agent.
