The invention relates to a non-aqueous fluoropolymer composition comprising: a) at least one fluorinated ionisable polymer [polymer (A)] as defined in the description, and b) at least one fluorinated ionisable polymer [polymer (B)] as defined in the description; c) at least one fluorinated solvent; and d) at least one alcohol. The invention further relates to a process for manufacturing the composition and to the use of the composition for preparing polymeric materials.
摘要:
The present invention provides a chromium-free surface treatment liquid which enables forming, on a metal material surface, a film excellent in corrosion resistance at bent portions of a steel sheet, solvent resistance, coating properties after alkaline degreasing, and sweat resistance. The surface treatment liquid contains a resin compound having a specific bisphenol skeleton, a cationic urethane resin emulsion, a silane coupling agent, an organic titanium chelate compound, a quadrivalent vanadyl compound, a molybdate compound, a fluorine compound, and water at predetermined proportions. The pH of the surface treatment liquid is in the range of 4 to 5.

摘要:
The present invention provides a method for producing a hot-dip galvanized steel sheet having a uniform surface appearance, excellent conductivity and corrosion resistance, and a chromate-free surface treatment coating film. A method of producing a hot-dip galvanized steel sheet includes applying, to a hot-dip galvanized steel sheet having a Ra of 0.5 to 2.0 µm and a PPI of 150 or more, a predetermined surface treatment agent, i.e., a surface treatment agent containing a specified resin compound, a specified urethane resin having cationy, a specified silane coupling agent having a functional group, a specified organic Ti chelate compound, and a tetravalent vanadyl compound at a specified ratio; and drying the surface treatment agent at a ultimate sheet temperature of 50°C to 180°C to form a surface treatment coating film with a coating weight of 0.2 to 1.0 g/m 2 on the surface of the steel sheet.
