The present invention employs alkyl polysilicate to form silicone-polyester-polysilicate hybrid compositions with an appropriate proportion to modify silicone-polyester resin, or directly adds the alkyl polysilicate at an appropriate proportion into silicone-polyester resin to produce a hybrid composition. The composition in high baking temperature forms a hybrid structure having good thermal resistance, especially, hot-oil resistance and hot hardness, and good adhesion to metals such as carbon steel, stainless steel and aluminum. The present invention can be used in the field of the protective coating for heat-resistant metal such as frying pans and electric irons to be a kind of novel heat-resistant composition having hybrid structure. The composition in accordance with the present invention comprises (A)silicone-polyester; (B)alkyl polysilicate and the structure thereof comprises (RO)3?Si?O?(Si(OR)2?O)n?R, where n=0?20 and R represents ?CH3, ?C2H5, ?C3H7, or ?C4H9. The composition mentioned above comprises the compounds of (A) and (B) or the copolymer comprised by (A) and (B).
