A Teflon coat can be applied using traditional spray equipment and techniques. It is undertaken using a spray machine that utilizes compressed air for paint application. The coating is put into a spray gun, which is then held perpendicular to the surface being coated and sprayed in a rectangular motion.

It's not just Teflon that's dangerous though.... other cookware that may contain PTFE include T-Fal, Silverstone, Flura, Excalibur, Supra, Xylon, Greblon, Resistal, Duracote, Autograph and Scanpan. However, pans such as ceramic coated, hard anodized aluminum, and a well seasons cast iron can also be non-stick.

Teflon™ PTFE is FDA Food Grade compliant. ... PTFE mechanical properties are low compared to other advanced engineering plastics, but its properties remain useful over a temperature range of -400° F to 400° F forming its broad operating range suitable for many applications. PTFE can be used as low as - 436º F (-260 C ).
