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 3 Keys to Proper Coating Application

Examples of Coating Problems Caused

Peeling Peeling or flaking is usually caused by improper surface preparation, or too low a cure temperature.
Blisters Blisters are usually caused by coating applied too thickly with too fast a film formation, too rapid evaporation of solvents, or increasing the part temperature too quickly.
