Title
(EN) Concentrated fluoropolymer dispersions stabilized with anionic polyelectrolyte dispersing agents
(ZH) 用阴离子型聚合电解质分散剂稳定的浓缩含氟聚合物分散体
Abstract
(EN)
An aqueous fluoropolymer dispersion comprising fluoropolymer particles having an average particle size of about 10 to about 400 nm. The dispersion has a solids content of at least about 35 to about 70 wt% and comprises about 0.03 wt% to about 10 wt% anionic polyelectrolyte dispersing agent based on the weight of fluoropolymer solids. The dispersion has a Gel Time of at least about 100 seconds.
