    Almost everyone has one in their family.  The only reason they are allowed to cook is the non-stick coating that makes cleanup easier.


    To make a non-stick coating, a waterborne phenoxy resin crosslinker and a fluoro polymer is combined and then used to coat a metal substrate.  After curing, the surface becomes non-stick.  One issue with non-sticks coatings is they have poor resistance to scratching.  Colloidal silica added to the coating composition can improve the mechanical properties and make a more durable non-stick coating.  The result is a cooking surface that will last longer - maybe even long enough for them to take a cooking class
