Abstract
The invention provides a non-flammable cleaning composition comprising (a) a major amount of one or more highly fluorinated compounds having a boiling point less than about 100° C.; (b) a minor amount of one or more fluorinated compounds containing at least one aromatic moiety and having a boiling point between about 100° C.and about 140° C.; and (c) a minor amount of trans-1,2-dichloroethylene.
Claims15
A non-flammable composition comprising:
- (a) about 50 to about 90 weight percent of one or more highly fluorinated compound(s) selected from the group consisting of fluorinated ethers and hydrofluorocarbons having a boiling point less than about 100° C.;
- (b) about 5 to about 35 weight percent of one or more fluorinated compound(s) selected from the group consisting of mono-, di-, and tiialkyl aromatic compounds and having a boiling point between about 100° C. and about 140° C.;
- and
- (c) about 0.5 to about 30 weight percent of trans-1,2-dichloroethylene.
A non-flammable composition comprising between about 75 and about 80 weight percent of one or more hydrofluoroether(s), between about 10 and about 23 weight percent benzotrifluoride, and between about 2 and about 10 weight percent trans-1,2-dichloroethylene.
A non-flammable composition comprising between about 80 and about 85 weight percent of one or more hydrofluoroether(s), between about 10 and about 18 weight percent benzotrifluoride, and between about 2 and about 10 weight percent trans-1,2-dichloroethylene.
A non-flammable composition comprising between about 57 and about 73 weight percent of one or more hydrofluoroether(s), between about 10 and about 25 weight percent hexafluoroxylene, and between about 10 and about 20 weight percent trans-1,2-dichloroethylene.
A non-flammable composition comprising between about 70 and about 90 weight percent of one or more hydrofluorocarbon(s), between about 5 and about 20 weight percent benzotrifluoride, and between about 0.5 and about 15 weight percent trans-1,2-dichloroethylene.
