The list does not address all critical ingredients. Use only detergents
that meet the prescribed requirements.
Use of n-butyl acetate with non-inflammable paints
N-butyl acetate can also be found under the following names:
- Butyl acetate (ButAc)
- Butyl ethanoate
- N-butyl acetate
You may use butyl acetate (cleaning by hand with a cloth) non-
flammable paints for gentle manual precleaning.
Requirements for external cleaning of the atomizer body with ButAc:
- No continuous load (e.g. plastics not to be immersed in ButAc)
- Maximum load temperature 25 °C
- No re-distilled ButAc or ButAc with extenders (e.g. aromatic
hydrocarbons and their derivatives)
- Gentle cleaning (cleaning cloth moistened with ButAc)
- Subsequent drying and re-cleaning with iso- or n-propanol
