The azeotropy composition constituent and the azeotropy way the composition constituent and mixed composition constituent

摘要

PROBLEM TO BE SOLVED: To provide a solvent composition which is effective for removing oils and fats and dust, does not exert influences on a wide range of substrates including acrylic resins and has a moderate dissolving power.;SOLUTION: The azeotropic solvent composition comprises 69 mass% of (2,2,2-trifluoroethoxy)-1,1,2,2-tetrafluoroethane and 31 mass% of (perfluorobutoxy)methane. The azeotrope-like solvent composition 55-85 mass% of (2,2,2-trifluoroethoxy)-1,1,2,2-tetrafluoroethane and 15-45 mass% of (perfluorobutoxy)methane. The mixed solvent composition comprises 30-90 mass% of (2,2,2-trifluoroethoxy)-1,1,2,2-tetrafluoroethane and 10-70 mass% of (perfluorobutoxy)methane.;COPYRIGHT: (C)2006,JPO&NCIPI
