摘要:
Disclosed herein are a solvent composition and methods of using the solvent composition. The solvent composition includes at least 80 wt.% of trans-1,2-dichloroetheylene (t-DCE), and 0.1 to 20 wt.% of at least one organic compound. The organic compound may be a hydrocarbon and/or an oxygenated solvent. The solvent composition may be used to clean a surface by contacting the surface with the composition to dissolve a contaminant on the surface. The composition may be used to remove a coating from a surface of a substrate by contacting the surface with the solvent composition to dissolve the coating and removing the composition containing the coating from the surface. The composition may also be used to deposit material on a substrate by dissolving the material in the solvent composition, applying the composition containing the material onto the substrate, and evaporating the composition from the substrate.
摘要:
The present invention relates, in part, to compositions including at least one hydrofluoro-olefin or hydrochlorofluoro-olefin solvent. Such compositions may optionally contain one or more alcohols or other co-solvent or agent and may be used to provide one or more cleaning applications.
摘要:
Incombustible fluorinated hydrocarbons excellent in detergency and stabilities to alkalis, water and heat; and polymer-containing fluids obtained by dissolving or dispersing a film-forming polymer, preferably a fluoropolymer in a solvent containing a trihydrofluorocarbon. Specifically, fluorinated hydrocarbons containing at least 95 % of trihydrofluorocarbons represented by the following general formula and having 4 to 6 carbons; and polymer-containing fluids each containing the fluorinated hydrocarbon: Rf1-R1-Rf2 wherein R1 is a carbon chain composed of CHF and CH2; and Rf1 and Rf2 are each perfluoroalkyl, or Rf1 and Rf2 are bonded together to form a ring.
摘要:
A combination of stabilizers and bromochloromethane are used as a cleaning composition in which the bromochloromethane is stabilized against decomposition and the release of bromine into the atmosphere.
