If teflon is in the liquid phase or in the solution, dip coating might be very easy and cheap.

Dimitar P. Mitev

You may try dipping into these suspensions (several times if necessary), with subsequent heating/melting:

PS: There are also soluble PTFE-like copolymers; check the page for Teflon AF

Paul P. Herrmann

Visit DUPONT site ->

http://www2.dupont.com/KIV/zh_CN/assets/downloads/DuPont_Teflon_AF_Processing_and_Use_K26986_H44015.pdf

Visiting the link, you will find amorphous fluoropolymers (AF) solvable in appropriate solvents, then use sort of dip coating to apply the AF on your PT-wire.

Good luck!
