US 2010/0029531 A1 · Nonflammable compositions comprising fluorinated compounds and use of these compositions

Abstract

The invention relates to non-flammable compositions comprising fluorinated compounds selected from the group consisting of hydrofluoroalkanes, hydrofluoroalkenes, partially or perfluorinated aromatic compounds, hydrofluoroethers or fluoroketones, 1,2-dichloroethylene, especially trans-1,2-dichloroethylene, and a stabilizer. These non-flammable compositions which preferably contain 1,1,1,3,3-pentafluorobutane, can be used especially as solvents for cleaning and defluxing electronic components and for degreasing metals. The compositions further may comprise a propellant, e.g. 1,1,1,2-tetrafluoroethane. These compositions are especially suitable as flushing agent.
