Abstract
Multi-component compositions comprising as a first component a fluorinated compound, as a second component a fluorinated aromatic compound and a third component comprising an alkane are disclosed. These compositions can be formulated to provide single phase systems which serve as effective solvents for fluorinated oils as well as petroleum oils. The compositions can serve as solvent cleaners or can be combined directly with oils to provide a delivery system for the oil.
