ABSTRACT:
The present invention relates to compositions comprising fluorinated olefins or fluorinated ketones, and at least one alcohol, halocarbon, hydrofluorocarbon, or fluoroether and combinations thereof. In one embodiment, these compositions are azeotropic or azeotrope-like. In another embodiment, these compositions are useful in cleaning applications as a degreasing agent or defluxing agent for removing oils and/or other residues from a surface.
