Abstract:
To provide a solvent composition capable of removing soils such as dusts and oils attached to the surface of an article made of an acrylic resin or an article coated with an acrylic resin, without damaging it.An azeotrope-like solvent composition comprising from 38 to 41 mass % of (2,2,2-trifluoroethoxy)-1,1,2,2-tetrafluoroethane and from 59 to 62 mass % of perfluorohexane. A mixed solvent composition comprising from 30 to 60 mass % of (2,2,2-trifluoroethoxy)-1,1,2,2-tetrafluoroethane and from 40 to 70 mass % of perfluorohexane.
