- Fluorinating a surface or applying a fluorinated coating lowers the surface energy and makes the surface more hydrophobic. Desbief et. al.  discuss this idea in terms of polymer coatings, "introduction of fluorine atoms substantially reduces the surface energy of the polymer film."
- Many companies make fluorinated plastic containers which are less permeable than simple HDPE containers.
