  • Publication number: 20100227173
    Abstract: Disclosed is a water-repellent oil-repellent antifouling agent containing a fluorine-containing polymer for a treatment for providing water repellency, oil repellency and antifouling property. The fluorine-containing polymer has a repeating unit (A) derived from a fluorine-containing acrylate monomer, and a repeating unit (B) derived from at least one non-fluorine acrylate monomer selected from the group consisting of a monomer (B1) having a cyclic hydrocarbon group and a monomer (B2) having a short chain hydrocarbon group. This water-repellent oil-repellent antifouling agent has good solubility in solvents, and exhibits excellent effects on various bases, especially on masonries.
