Teflon Dispersions

DuPont™ Teflon® aqueous dispersions are milky white dispersions of PTFE particles in water, stabilized by wetting agents.  They can be further formulated to meet specific needs by adding other solid or liquid ingredients.  These aqueous dispersions offer a practical method for coating or impregnating using a resin that does not respond to traditional solvent or melt-processing techniques.

Fuel Cell Applications:  Teflon, like the Nafion, acts as a binding agent and sometimes replaces the Nafion solution for that purpose because it is less expensive.  Also, coating the gas diffusion layer with Teflon prevents the gas diffusion layer from being saturated by liquid water, while still letting water vapor through the pores.
