How long will the Teflon non-stick coating last?

We get a lot of questions about the life expectancy of our Teflon coatings. The best answer is it depends on how the product is taken care of during your process. unfortunately, Teflon has been given a bad name in some machine operators eyes because it can be scratched easily. Which will eventually cause problems in the the adherence of the non-stick coatings because solvents and cleaning solutions will get between the coating and metal substrate.
The good news is that there have been several advances in non-stick coatings make up to make it more durable and scratch resistant. For example, there is a ceramic reinforced Teflon that can be considered a wear resistant coating. Operators will still want to be cautious with Teflon or non-stick products making sure to use plastic clean-up utensils, but you should expect a fairly long life our of your teflon or non-stick coating. You can expect a much longer life out of an industrial applied non-stick coating than that of a non-stick tape or spray on.
Once coatings are applied and in operation. You will see a very slow change in the release of the coating that could take years depending on the care of the Teflon. The coating will be at a 100% release day 1, and will continue to release your substrates a little less over time until you would want to get it re-coated again. Again, this slow change in release can take 6 months to a number of years depending on what your process is.
