The azeotropy way way the composition constituent and mixed composition

摘要

From the surface of the acrylic resin member or members made of acrylic resin is coated, without affecting the member, providing a solvent composition capable of removing dirt dust and oils and fats. And 38-41 mass% (2,2,2-trifluoro-ethoxy) 1,1,2,2-tetrafluoroethane, azeotrope-like solvent composition consisting of 59-62% by weight perfluorohexane. A mixed solvent composition comprising (2,2,2-trifluoroethoxy) -1,1,2,2-tetrafluoroethane 30 to 60% by weight, and 40 to 70% by weight perfluorohexane.
