摘要:
The present invention provides a solvent composition that can inhibit corrosion of a metal, a cleaning method using the solvent composition, and a method for producing an article provided with a coating film. The solvent composition of the present invention comprises 1-chloro-2,3,3-trifluoropropene and a specified second component, and is characterized in that the proportion of the total amount of the content of the second component to the sum of the content of 1-chloro-2,3,3-trifluoropropene and the total amount of the content of the second component is from 0.0001 to 1.0 mass%.
摘要:
The invention provides solvent and cleaning compositions comprising an ionic surfactant, which preferably has a fluorinated portion thereof, and a solvent selected from hydrofluoro- and/or hydrochlorofluoro-olefins. Additionally, the invention provides drying, dry cleaning, and soil repellency compositions containing a hydrofluoro- or hydrochlorofluoro-olefin and said surfactant. Additionally, the invention provides drying compositions containing a hydrofluoro-olefin or hydrochlorofluoro-olefin and an alcohol such as methanol, ethanol or isopropanol.
摘要:
Disclosed are compositions comprising 90 to 99 weight percent trans-1,2-dichloroethylene, from 0.1 to 8 weight percent methylperfluoroheptene ethers and from 0.1 to 2.0 weight percent of 1,1,1,2,2,3,4,5,5,5-decafluoropentane, wherein the composition is non-flammable. The disclosure further provides a method for removing residue from a surface of an article comprising: (a) contacting the article with a composition comprising a composition of MPHE, HFC-4310mee and trans-1,2-dichloroethylene; and (b) recovering the surface from the composition.
摘要:
The invention relates to certain compositions of hydrofluoroalkanes, hydrofluoroalkenes, hydrofluoroethers or hydrofluoroketones with 1,2-dichloroethylene and fatty acid esters as well as mixtures comprising these compositions and the use of the same especially as cleaning and/or drying agents for solid surfaces and for flushing, especially of refrigeration systems.
摘要:
The present invention relates, in part, to cleaning methods and solvent cleaning compositions including at least one hydrofluoro-olefin or hydrochlorofluoro-olefin solvent for use in connection with cleaning of metal parts, and in certain preferred embodiments cleaning metal parts to be used in an aircraft.
