There are two major types of nonstick coatings: fluoropolymer and silicone coatings. They are differentiated by the ingredient used to provide the nonstick characteristic.

Fluoropolymer Coatings use any of a number of fluoropolymer resin compounds (principally PTFE) that are solid, non-toxic plastic polymers having inherent nonstick properties. [To learn more about fluoropolymers, make sure to read the PKN course on PFOA.]

Reasons for use: Fluoropolymer coatings retain the nonstick quality far longer and, with advances in coating technology, they are far more resistant to wear. Fluoropolymer coatings are primarily used on cookware and small electric appliances.

Silicone Coatings use non-toxic synthetic resins that can be applied to specially prepared metal surfaces and bonded to the metal by baking. Unfortunately, they tend to lose their nonstick characteristic sooner than fluoropolymer coatings, and they do not withstand wear very well.

Reasons for use: Silicone coatings are cheaper and are primarily used on bakeware and low-end cookware.

Are there different kinds of nonstick coatings?

There are three major types of nonstick coatings: fluoropolymer, silicone and sol-gel “ceramic” coatings. They are differentiated by the ingredient used to provide the nonstick characteristic.

Fluoropolymer Coatings use any of a number of fluoropolymer resin compounds (principally PTFE) that are solid, non-toxic plastic polymers having inherent nonstick properties.

Reasons for use: Fluoropolymer coatings retain the nonstick quality far longer and, with advances in coating technology, they are far more resistant to wear. Fluoropolymer coatings are primarily used on cookware and small electric appliances.

Reasons for use: Silicone coatings are cheaper and are primarily used on bakeware and low-end cookware.

Sol-Gel "Ceramic" Coatings: Sol-gel is a hybrid material. Because of its chemical nature it possesses the strength of silica while achieving excellent smoothness and good release without fluoropolymers. Coatings produced using sol-gel technology are more accurately described as ceramic-like; they feature many of the same characteristics as ceramic but to a lesser extent. The release agent or nonstick ingredient is embedded in the coating

Reasons for use: Sol-Gel coatings became popular due to its high temperature resistance, PFOA free claims and light, bright colors that can be achieved.
