Coated aluminum pan is the most basic kitchen utensil, which has the characteristics of light weight and low production cost. In addition, compared to expensive cast iron or stainless steel pans, aluminum pans use less oil, and use it to make fish, egg rolls and pancakes with much lower fat content. This also satisfies modern consumers who pay attention to healthy eating. Demand. But for a long time, aluminum pans have always had an Achilles heel: poor heat resistance. For this reason, when making dishes that require high-temperature cooking, such as fried steaks, those picky chefs are more willing to choose other metal pans. However, in this regard, aluminum pans are constantly improving: usually the inner surface is coated with polytetrafluoroethylene, which is known as Teflon, and the outer surface is coated with silicone polyester resin.

During the baking process, after the moisture in the coating evaporates, the coating is heated continuously at a temperature of 250 °C to 280 °C for about 10-15 minutes to complete the cross-linking reaction. Silicone resin is used as a base material to wrap the solid particles in the coating  ——  pigments and fillers  ——  , so that they are firmly bonded to each other and to the substrate, thereby forming a strong coating to protect the product from Subject to external influences.

Silicone resin coatings that do not contain organic components have better heat resistance: if pigments and fillers are added, such coatings can even withstand high temperatures above 650 °C for a short time. If a silicone resin that has not been organically modified is used, the heat resistance of the coating will be unmatched, and this coating can also be used for engine parts.
