Zusammenfassung: | PURPOSE:To obtain the solvent compsn. for draining which has no possibility of the destruction of the ozone stratra and has an excellent draining capacity by dissolving and mixing perfluorodimethyl cyclobutane and 2, 2, 3, 3, 3- pentafluoropropanol. CONSTITUTION:The solvent compsn. for draining contg. the perfluorodimethyl cyclobutane and 2,2,3,3,3-pentafluoropropanol enhances the draining effect of articles by making combination use of C-51-12 and 5FP. Further, the water solubility of the solvent compsn. for draining is lowered than the water solubility of the 5FP alone and the generation of stains on the metallic surface by the remaining of water is suppressed. The concn. of the 5FP is preferably |
