Where did it all begin?

Nonstick coatings hit the selling floors in the early 1960s.

The first nonsticks were made primarily of polytetrafluoroethylene (PTFE). PTFE has the lowest coefficient of friction (CoF) of any known solid. In other words, the majority of materials (in this case foodstuffs) do not stick to it.

PTFE's low CoF "releases" the materials, making it easy to separate them from the coating. Therefore, on nonstick pans, most substances are easily removed from the surface.

Unfortunately, PTFE is also very soft and, if unprotected, wears quickly. While early nonsticks had good release, they were soft and wore out after little use. The result: nonstick-coated cookware earned the reputation of being "disposable".

The Curing Process

Oven Load

This is an aspect of curing whose importance is often underestimated. The more put into an oven, the longer the cure will take - and the greater the chance of having an uneven cure. As greater mass enters an oven, the effective temperature is reduced. So a heavy load in a line oven may require slowing the belt, just as a full batch oven may require additional time.

There are so many variables in the curing process that achieving a perfect cure is not always easy, but with the right tools and support from the coating supplier, it can be achieved.
