AQUEOUS DISPERSION OF FLUORINE-CONTAINING RESIN, AQUEOUS COMPOSITION OF FLUORINE-CONTAINING RESIN, COATING MATERIAL AND FILM

摘要

PROBLEM TO BE SOLVED: To provide an aqueous dispersion of a fluorine-containing resin, having excellent mechanical stability, suitability for recoating and processability without damaging dispersibility and dispersion stability; and to provide an aqueous composition of the fluorine-containing resin. SOLUTION: The aqueous dispersion of the fluorine-containing resin comprises a fluoropolymer, an aliphatic polyoxyalkylene ether surfactant (A) and an aliphatic polyoxyalkylene ether surfactant (B). The content of the mass of the solid component of the fluoropolymer is 30-65% based on the total mass of the aqueous dispersing agent of the fluorine-containing resin, and the surface tension of the aliphatic polyoxyalkylene ether surfactant (A) is higher than that of the aliphatic polyoxyalkylene ether surfactant (B). The total mass of the surfactants (A) and (B) is 2-20% based on the mass of the solid component of the fluorine-containing resin. The mass of the surfactant (A) is not less than 50% and less than 100 wt.% of the total mass of the surfactant (A) and (B). COPYRIGHT: (C)2004,JPO
