摘要
A stabilized aqueous fluoropolymer dispersion comprising fluoropolymer particles, wherein the dispersion contains less that about 300 ppm fluorosurfactant based on the weight of the dispersion and a cationic surfactant. The cationic surfactant aids in reducing the viscosity of the dispersion and preferred cationic surfactants are volatile in coating or film casting operations involving drying and sintering of the dispersion.
