Abstract
A solvent composition and method for making same is disclosed having a composition between 26 to 90 weight percent propionate, butyrate, or combination thereof and between 10 to 74 weight percent fluorinated solvent blend, wherein the fluorinated solvent blend includes t-DCE. A polymer solvent system is also disclosed incorporating the solvent composition and dissolved polymers, such as SEBS polymers. The solvent composition and polymer solvent system is minimally combustible or preferably nonflammable.
Claims52
A solvent composition comprising
- between 60 to 90 weight percent of a butyrate, and
