Nonstick coating is a type of material used to coat surfaces to prevent sticking. The most common nonstick coating is TEFLON, which is a synthetic fluoropolymer that was first developed in 1938. TEFLON is used in many applications, including cookware, as it is resistant to heat and corrosion. It is also used in industrial applications, such as in the aerospace industry, where it is used to coat parts to reduce friction and wear. TEFLON is a safe and effective nonstick coating that is widely used in many industries.
