Disclosed is a novel noncombustible solvent composition which can remove an oil-and-fat attached to an article such as an electronic component (e.g., IC), a precision machinery component, a glass substrate or the like or a flux or soil (e.g., dust) on a print circuit board or the like. A mixed solvent composition comprising 40 to 90% by mass of 1,1,1,2,2,3,3,4,4,5,5,6,6-tridecafluorooctane and 60 to 10% by mass of isopropanol; and an azeotropic solvent composition comprising 62% by mass of 1,1,1,2,2,3,3,4,4,5,5,6,6-tridecafluorooctane and 38% by mass of isopropanol.
摘要:
The invention relates to a method of cleaning a solid surface comprising the following stages: a) the solid surface is cleaned using a microemulsion-type cleaning composition; e) the cleaned surface is drained; f) the drained surface is rinsed with an organic solvent or a mixture of organic solvents with a low boiling point; and g) said surface which was rinsed with the organic solvent or the mixture of organic solvents used in c) is then dried.
