Composition for Dust-Preventive Treatment |
摘要 |
A composition for dust-preventive treatment including an aqueous dispersion of fluorine-containing polymer showing a low potential for environmental concerns and a dust prevention effect as high as that of known composition for dust-preventive treatment. The composition for dust-preventive treatment includes an aqueous dispersion of fluorine-containing polymer containing 50 ppm or less of a fluorine-containing emulsifier. The composition for dust-preventive treatment comprising aqueous dispersion of fluorine-containing polymer containing 50 ppm or less of a fluorine-containing emulsifier can preferably be obtained by removing the fluorine-containing emulsifier from a polymer dispersion prepared by polymerizing tetrafluoroethylene using the fluorine-containing emulsifier.
