Maybe the underside of a piece of teflon is not non-stick? And they use double sided tape or 'No more nails' to keep it on. Any way it doesnt last for ever. My teflon pans are knackered now and Ive only been using them 25 years. Tsk.

The basic non-stick molecule is a polymer, or chain, of fluorine atoms and additives such as carbon and hydrogen. The longer this chain, the tougher it is; but a molecule that's too long gets viscous and hard to handle.
To move beyond mere mechanics, the frying-pan engineers added a sticky molecule to the non-stick molecule. Non-stick was now applied in coats, with the bottom coat containing the sticky additive that held to both the metal pan and the non-stick molecules. A coat of non-sticky non-stick went over that, non-stick and non-stick clinging together lovingly. A final non-stick layer, spiked with teensy bits of ceramic or other tougheners, protected the softer guts.
This is how lots of non-sticks are made still: Grit-blast the pan; spray on a sticky primer coat, a midcoat, and a tougher top coat; and bake. Oh, yeah: Add colors if you like -- the fluoropolymer is naturally white, but cooks prefer somber saucepans. You may also add a handful of mica, a sparkly rock, to glimmer up the finish.
But the latest non-stick revolution, probably lost on cooks, is a non-mechanical means of sticking non-stick to aluminum. In this method, which DuPont calls "smooth technology," new-and-improved sticky molecules in the primer coat sink as the pan bakes and chemically lock themselves to smooth, unmolested metal. The upper layers fuse together better, and you get a tougher pan.

It's applied electrostatically, that is that the pot or pan has an electrical charge running thru it that attracts the Teflon, which has an opposite electrical charge ... it's like a magnet. The auto industry paints cars the same way.

The teflon coating is "melted" on at very high temperature. At high temperatures, it gets liquid and grabs onto the microscopic holes in the metal of the pan. After cooling, it's completely bonded to the surface.

They superheat each thing throughout production, in line with risk. the two way, teflon is undesirable for you. The vapors it emits throughout heating can kill birds. This occurred on the San Diego Zoo whilst they commencing coating warmth lamps with teflon, they lost like 2 hundred birds. forged iron is the place that is at. that is nonstick with out each and all of the unusual chemical components entering into your physique.

It is melted or formed into the base metal, the pores of that metal grasping the teflon and locking it in place.

there is a primer applied to the metel before the teflon is applied.
