How does it stick?

From:  "Joe Johnson"

If Nothing Sticks To Teflon Then How Do They Stick It To The Pan???

TB came to this conclusion: 

Originally it didn't stick well - you had to use special utensils or the Teflon would chip off.  Today, they roughen the pan's surface by sandblasting it. A primer is applied to the surface and then the Teflon is embedded in the primer.

pavolka thought up this idea: 

It's like duct tape. one side is sticky, the other isn't.

the saint agreed with TB and pavolka: 

I believe it's a high-temperature process that fuses it to the surface, or else it's deposited by some sort of carrier that evaporates, as in paint.
