摘要： A nonflammable solvent composition, a method of cleaning an article, and a method of depositing a material on a substrate are disclosed. The nonflammable solvent composition includes a fluorocyclopentane in which 3 to 9 hydrogen atoms have each been replaced by a fluorine atom; trans-1,2-dichloroethylene (t-DCE); and at least one organic compound, such as a C2-C6 alcohol, a C1-C6 alkane, and a C3-C6 cycloalkane. Amounts of the fluorocyclopentane, t-DCE, and the organic compound in the nonflammable composition are selected so that the composition is an azeotrope or is azeotrope-like. The method of cleaning an article includes contacting the article with the nonflammable composition via vapor degreasing or wet cleaning. The method of depositing a material on a substrate includes dissolving the material in the nonflammable solvent composition, applying the composition containing the material to the substrate, and evaporating the composition from the substrate.

摘要： Disclosed herein are solvent compositions and methods of using the solvent compositions. The solvent composition includes at least trans-1,2-dichloroethylene (t-DCE) and 1,1,2,2-tetrafluoroethyl-2,2,3,3-tetrafluoropropyl ether (TFE-TFPE). The solvent composition may also include an oxygenated solvent, such as an alcohol or fluorinated ether. A method of cleaning the surface of an article includes contacting the surface with the solvent composition to dissolve, disperse, or displace a contaminant on the surface, and removing the solvent composition containing the contaminant from the surface.

摘要： A nonflammable solvent composition, a method of cleaning a surface, and a method of coating a substrate with a material using the solvent composition are provided. The nonflammable solvent composition includes about 70 wt. % or more of trans-1,2-dichloroethylene (t-DCE) and about 0.1 to about 30 wt. % of one or more of hydrofluoroether (HFE) and n-propyl bromide. The method of cleaning a surface includes applying the solvent composition to the surface and spreading or rubbing the composition on the surface. The method of coating a substrate with a material includes dissolving one or more material in the solvent composition, applying the solvent composition containing the one or more material to a substrate, and evaporating the solvent composition from the substrate.
