| abstract |
A fluoropolymer-base, water- and oil-repellent composition of an aqueous dispersion type, prepared by dispersing a polymer comprising an ethylenically unsaturated monomer having a perfluoroalkyl group in an aqueous medium, which composition contains a nonionic surfactant having an HLB value of 11 or below and a cationic surfactant, with at least one of the constituent monomers of the polymer being one forming a homopolymer having Tg of 50°C or below. The composition is excellent in the water- and oil-repellency given by low-temperature curing. |
