Dupont Teflon

DuPont Teflon® is an incredible coating that was developed by Dr. Roy J. Plunkett for DuPont Chemical.

According to Wikipedia, "PTFE was accidentally discovered in 1938 by Roy Plunkett, in New Jersey while he was working for Kinetic Chemicals (a company owned by DuPont). As Plunkett was attempting to make a new chlorofluorocarbon refrigerant, the tetrafluoroethylene gas in its pressure bottle stopped flowing before the bottle's weight had dropped to the point signaling "empty." Since Plunkett was measuring the amount of gas used by weighing the bottle, he became curious as to the source of the weight, and finally resorted to sawing the bottle apart. Inside, he found it coated with a waxy white material which was oddly slippery. Analysis of the material showed that it was polymerized perfluoroethylene, with the iron from the inside of the container having acted as a catalyst at high pressure. Kinetic Chemicals patented the new fluorinated plastic (analogous to known polyethylene) in 1941, and registered the Teflon trademark in 1945."

Teflon coatings are used for many purposes related to outdoor gear.

According to the DuPont Website:

"DuPont™ Teflon® fabric protector helps keep garments looking new longer, no matter what life throws at them. See how Teflon® brand repellents and stain protective finishes keep fashions looking new and easy to care for . . . fabrics treated with DuPont™ Teflon® fabric protector outsmart stains by fending off unsightly splashes and spots, day after day, in a variety of applications."

For the outdoors person and Browning customer this can be a great thing, improving performance of top end technical wear over the years.

Teflon coatings also improve performance of products like knife blades, where it makes them resist staining and provides a more non-stick surface.

There is a great article about Teflon on Wikipedia, but it is pretty complex for most of us. To read the Wikipedia "Teflon" article click here.
