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.
