Abstract
To provide a solvent composition in which various organic substances are soluble, and which has no adverse effect on global environment. A solvent composition comprising 1-chloro-2,3,3,4,4,5,5-heptafluoro-1-pentene, a cleaning method using the solvent composition, a method for producing a substrate with a coating film, and a heat transfer fluid.
Claims20
A method for producing a substrate with a coating film, comprising:
- dissolving a nonvolatile substance in a solvent composition comprising 1-chloro-2,3,3,4,4,5,5-heptafluoro-1-pentene, thereby obtaining a coating film-forming composition;
- applying the coating film-forming composition to a substrate;
- and
- evaporating the solvent composition, thereby forming a coating film containing the nonvolatile substance on the substrate,
- wherein in the 1-chloro-2,3,3,4,4,5,5-heptafluoro-1-pentene, a proportion of a content of (Z)-1-chloro-2,3,3,4,4,5,5-heptafluoro-1-pentene to a total amount of (Z)-1-chloro-2,3,3,4,4,5,5-heptafluoro-1-pentene and (E)-1-chloro-2,3,3,4,4,5,5-heptafluoro-1-pentene is at least 50 mass %, and
- in the solvent composition, a proportion of a content of 1-chloro-2,3,3,4,4,5,5-heptafluoro-1-pentene to a total amount of the solvent composition is at least 50 mass %.
