Definitions

  • the present invention relates to a composition for cleaning and cold degreasing of solid surfaces in a non-aqueous medium, said composition comprising at least one mixture of alkanes or cycloalkanes, at least one halogenated organic compound, in particular fluorinated or perfluorinated and at least one organic compound comprising one or more functions oxygenated.
  • This composition can be used in particular for applications of degreasing of solid surfaces such as metal parts, cement, ceramic, glass, synthetic materials having been soiled by oils or greases for machining and / or their temporary protection.
  • This composition can also be used for defluxing printed circuits. This defluxing operation consists in eliminating the flow of welding.
  • hydrocarbons and mainly chlorinated solvents such as in particular 1,1,1-trichloroethane known in the art under the designation T 111, chlorofluoroalkanes such as 1,1,2-trichloro-1,2,2-trifluoroethane known in the trade under the designation F113 and hydrochlorofluoroalkanes (HCFC) such than 1,1-dichloro-1-fluoroethane (141-b).
  • chlorinated, fluorochlorinated and hydrochlorofluorocarbon compounds are believed to be responsible for the shrinking layer stratospheric ozone which provides protection against certain radiations.
  • a cold cleaning and degreasing composition for a solid surface in a non-aqueous medium characterized in that it consists of at least one organic compound (A) chosen from the group consisting of perfluoro- (N -alkylmorpholines), n-tridecafluorohexane (C 6 F 13 H), 2,3-dihydrodecafluoropentane (C 5 H 2 F 10 , 4310 mee), 3,3,4-trihydroheptafluorobutane (C 4 F 7 H 13 , 347 mcf), 2,2,4,4,4-pentahydropentafluorobutane (C 4 F 5 H 5 , 365 mcf), perfluoroalkanes, hydrofluoroalkenes, chloromethanes, fluorinated ethers, at least one mixture of alkanes or cycloalkanes (B), and at least one organic compound (C) chosen from the group consisting of ketones
  • Rf and R 1 f which are identical or different, represent a linear or branched perfluorinated aliphatic radical, having a carbon number ranging from 1 to 4, n is a number ranging from 0 to 8, and the symbol F inside of the ring means that the saturated ring is completely fluorinated, that is to say that all of the carbon atoms are linked to fluorine atoms (or to R 1 f).
  • perfluoroalkanes which can be used according to the invention, mention may be made of n-perfluorohexane (C 6 F 14 ).
