Disclosed herein are blowing agents comprising fluorocarbons and/or hydrofluorocarbons useful in foamable compositions. Also disclosed are methods for forming a foam comprising the aforementioned blowing agents.
This invention relates to cleaning compositions comprising unsaturated fluorinated hydrocarbons. The invention further relates to use of said cleaning compositions in methods to clean, degrease, deflux, dewater, and deposit fluorolubricant. The invention further relates to novel unsaturated fluorinated hydrocarbons and their use as cleaning compositions and in the methods listed above.
Disclosed herein are propellants comprising fluorocarbons and/or hydrofluorocarbons. Also disclosed are sprayable compositions comprising the propellants.
Disclosed is a method for removing residue from a surface comprising: contacting the surface with a composition comprising at least one unsaturated fluorinated hydrocarbon selected from the group consisting of compounds having the formula E- or Z—R
1
CH═CHR
2
, wherein R
1
and R
2
are, independently, C
1
to C
6
perfluoroalkyl groups, or C
1
to C
6
hydrofluoroalkyl groups, and recovering the surface from the composition.
