The present invention concerns the field of fluorinated hydrocarbons and
relates to novel compositions containing fluorinated hydrocarbons and
oxygenated solvents. More particularly, the compositions comprise a
fluorinated base, diacetone alcohol (DAA), and DMSO and/or secondary
butanol. These novel compositions can be used in particular in all
solvent applications of HCFC 141b (hydrochlorofluorocarbon 141b), in
particular in various operations for treating solid surfaces, such as the
cleaning, degreasing, defluxing or drying of solid surfaces.
