Abstract
An aqueous fluorine-containing polymer dispersion, which comprises a fluorine-containing polymer, a nonionic surfactant and a preservative having at least one halogen atom on a carbon atom having an electron attractive group or a preservative having methylol group or methylene group and releasing formaldehyde, is provided. The above-mentioned dispersion is free of putrefying odor and suspended matters, is excellent in stability for a long period of time without pH decrease and does not generate any cissing and aggregation at the time of coating such as impregnation.
