Abstract:
A fluorine-containing surface treatment composition comprising a surface treatment component and a solvent component and adapted for use as a mold release agent, an electric wire stripping agent or a lubricant, wherein(I) the surface treatment component comprises at least one species selected from the group consisting of: (1) phosphorus-containing compounds having at least one fluorine-containing group selected from the group consisting of polyfluoroalkyl groups and polyfluoroalkenyl groups; (2) highly fluorinated organic compounds; and (3) polymers prepared using, as a monomer component, a compound having at least one fluorine-containing group selected from the group consisting of polyfluoroalkyl groups and polyfluoroalkenyl groups, said highly fluorinated organic compound (2) being at least one compound selected from the group consisting of: (A) at least one fluoroalkane selected from the group consisting of (CF3)2CF(CF2)4CF(CF3)2 and (B) at least one fluorochloro polyether selected from the group consisting of: F(CHClCF2CF2O)nCHClCF3 (n is 5 on an average); F(CCl2CF2CF2O)nCCl2CF3 (n is 5 on an average); F(CCl2CF2CF2O)nCCl2CF2Cl (n is 25 on an average); CCl2FCF2CF2OCCl2CF2CF2OCCl2CF3; F(CClxFyCF2CF2O)nCClxFyCF3 (n is 5 on an average), x+y=2, x:y=1:4); F(CF2CF2CF2O)x(CClFCF2CF2O)yâ€”CF2CF2COF (x+y is 20 on an average, x:y=2:1, x number of units and y number of units are arranged in a random order); and F(CF2CF2CF2O)x(CClFCF2CF2O)yCF2CF3 (x+y is 20 on an average, x:y=2:1, x number of units and y number of units are arranged in a random order), and (C) fluorochloroolefin telomers whose main portion, defined as a portion except for terminal groups, is composed of repeating units of â€”CF2CFClâ€”, the total of the repeating units of chlorotrifluoroethane in terms of degree of telomerization being 3 to 20, and said polymer (3) prepared using as, a monomer component, a compound having at least one fluorine-containing group selected from the group consisting of polyfluoroalkyl groups and polyfluoroalkenyl groups being at least one polymer selected from the group consisting of: â€ƒ(A) a copolymer of at least one fluorine-containing monomer selected from the group consisting of polyfluoroalkyl-containing (meth)acrylic esters, polyfluoroalkenyl-containing (meth)acrylic esters, polyfluoroalkyl-containing vinyl compounds and poly-fluoroalkenyl-containing vinyl compounds, and another monomer copolymerizable therewith, the proportion of the fluorine-containing monomer being 20-95 parts by weight, based on 100 parts by weight of the total monomer component, and â€ƒ(B) a polymer of at least one fluorine-containing monomer selected from the group consisting of polyfluoroalkyl-containing epoxy monomers and polyfluoroalkenyl-containing epoxy monomers, or a copolymer of the fluorine-containing monomer and another monomer copolymerizable therewith, the proportion of the fluorine-containing monomer being 20-100 parts by weight, based on 100 parts by weight of the total monomer component; and (II) the solvent component contains 5 wt. % or more of a chlorine-free, non-flammable halogen-containing solvent which has an ozone depletion potential (ODP) of 0.03 or less, a 100-year integrated global warming potential (GWP) value of 500 or less, and a kauri butanol (KB) value of 5 or more.
