Teflon coating is one of the commonly used protective coatings in metal thermal spraying processing technology services, with good non-stick, wear resistance, corrosion resistance, high temperature resistance and other characteristics, can be applied to carbon steel, stainless steel, aluminum, copper, magnesium and various alloys and other metal materials. It can also be applied to non-metallic materials such as glass, glass fiber and some rubber plastics. The characteristics of Teflon coating are as follows:

1.Non-stick: Teflon spray almost does not produce adhesion with any substance, only a thin layer on the surface of the appliance, in order to show its non-stick ability. So in food processing, Teflon is sprayed on baking utensils, baking pans, and molds. When sprayed with Teflon, these utensils are easily demoulded, so the processed pastry food is in the same shape. At the same time, the service life of these instruments sprayed with teflon can be extended.
