The invention relates to fluorinated hydrocarbons. The aim of the invention is to provide novel compositions containing fluorinated hydrocarbons and oxygenated solvents. More specifically, said compositions comprise a fluorinated base, diacetone alcohol (DAA), DMSO and/or secondary butanol. The novel compositions can be used in all HCFC 141b (hydrochlorofluorocarbon 141b) solvent applications, particularly in various operations for the treatment of solid surfaces such as the cleaning, degreasing, defluxing or drying of solid surfaces.
La présente invention concerne le domaine des hydrocarbures fluorés et a pour objet de nouvelles compositions contenant des hydrocarbures fluorés et des solvants oxygénés. Plus particulièrement, les compositions comprennent une base fluorée, du diacétone alcool (DAA), du DMSO et/ou du butanol secondaire. Ces nouvelles compositions sont utilisables notamment dans toutes les applications solvants du HCFC 141b (hydrochlorofluorocarbure 141b), en particulier dans diverses opérations de traitement de surfaces solides telles que le nettoyage, le dégraissage, le défluxage ou le séchage de surfaces solides.
