Silicone-polyester-coated aluminum pans can withstand cooking temperatures of 250 ºC for longer periods of time, and even 300 ° C for short periods of time.

In contrast, the heat resistance of traditional surface coating resins based on pure organic polymers is not very high, but if a polyester resin modified by silicone is used, the heat resistance of the coating will be significantly enhanced.

During the baking process, after the water in the coating evaporates, the coating is continuously heated at a temperature of 250 ° C to 280 ° C for about 10-15 minutes to complete the crosslinking reaction. Silicone resin is used as the base material, encapsulating the solid particles —— pigments and fillers —— in the coating to make them firmly adhere to each other and to the substrate to form a strong coating to protect the product from Affected by external influences.
