Non-Stick Coatings

Helping even the worst cooks

Non-stick coatings - cookware

Non-stick coatings have made cooking and household cleanup easier than ever before. Unfortunately, some non-stick coatings have a poor resistance to scratching and can tend to chip off. By adding colloidal silica to the composition of non-stick coatings, mechanical properties are improved, resulting in more durable non-stick coatings.

The most common non-stick coatings are created from organic (PTFE-based) or inorganic (ceramic-based) materials and are used for cookware. Other uses of non-stick coatings include bakeware, hair straighteners, and clothes iron surfaces.

When added to PTFE-based coating formulations (e.g., Teflon®), colloidal silica works as an adhesion promoter. While, when used to create ceramic non-stick coatings, colloidal silica acts as a co-binder. In both cases, colloidal silica helps increase surface temperature, hardness, and abrasion resistance properties of the resulting surface.
