FLUOROPOLYMER DISPERSIONS WITH REDUCED FLUOROSURFACTANT CONTENT AND HIGH SHEAR STABILITY

摘要

An aqueous dispersion comprising fluoropolymer particles, the aqueous dispersion having a fluorinated surfactant content of less than about 300 ppm and containing an aliphatic alcohol ethoxylate nonionic surfactant. The aliphatic alcohol ethoxylate surfactant is an ethoxylate of a saturated or unsaturated secondary alcohol having 8-18 carbon atoms.
