The coating of the cooking waffle maker is made of ceramics. According to relevant public information, ceramic coating can effectively prevent food from sticking to the baking tray and make the baked food more delicious. The main component of this coating is silicon dioxide, which has excellent wear resistance, corrosion resistance, high temperature resistance, anti-adhesion and easy cleaning. Compared with traditional coating materials such as PTFE, ceramic coating is not only more environmentally friendly and safer, but also more durable, easy to clean and has a longer service life.
