Teflon application in the home


I want to apply Teflon to the interior of a home rotisserie. Is there a spray-on or paint-on product that I can use without industrial equipment?

To make a Teflon coating you must "cure" the coating at 375º C. Normally at home we don't have the oven to obtain this temperature. You can find in the market paint that contains PTFE that can help you having a easy cleaning surface, but this paint do not last as long as a Teflon coating.

This response indicated that PTFE needs to be cured at 375 degrees C. It also indicates that home ovens cannot go that high. Self cleaning ovens will go higher to 482 degrees C.

Would this temperature destroy the PTFE coating and render it useless? The time at temperature can be controlled by unplugging the stove.

Your thoughts please.

Hi, Tim. You can name any material and there will be people who think it's dangerous to use, but I personally think it's safe to use Teflon coated cookware. That does not mean it's safe to cure Teflon at home. Do a search for 'parrot Teflon' and read about how the fumes from overheating Teflon is known to kill parrots. I think it is exceptionally risky to try to cure Teflon with the self-cleaning cycle of a home oven.

You probably cannot get the Teflon to adhere anyway. There is more to it than curing, the base aluminum requires the application of a special porous metallic coating to provide "key" so the Teflon will flow into the nooks and crannies so the Teflon will adhere.
