Aqueous 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.


What's New in Teflon® Dispersions ...
Using new polymer technology and a cleaner, more effective new wetting agent, DuPont introduces a new generation of high-performance Teflon® PTFE dispersion products.

Processing
Yard goods made from Teflon® aqueous dispersions can be dip-coated with repeated passes until the final desired thickness is obtained. The water is then removed and the other ingredients deactivated. The dried resin particles can be coalesced by heat into a continuous coating or the substrate can remain coated, or impregnated, with unmelted particles. Both glass fabric and synthetic substrates can be processed.
