An organic-inorganic hybrid resin is formed by reacting a polyol organic resin with a polysilsesquioxane polymer. The organic-inorganic hybrid resin has T, T, T, and Tsignals ofSi-NMR, wherein a ratio of the sum of 3 times the integral value of Tsignal and 2 times the integral value of Tsignal and the integral value of Tsignal and the integral value of Tsignal ((3T+2T+T)/T) is from 0.3 to 1.2, wherein the Tsignal range is 35 ppm to 40 ppm, the Tsignal range is 48 ppm to 53 ppm, the Tsignal range is 55 ppm to 62 ppm, and the Tsignal range is 63 ppm to 72 ppm.

Organic-inorganic hybrid resin, coating material, and composite structure

A polymer is provided, which is formed by reacting a diol having hydrogenated bisphenol group with a bis-epoxy compound. The diol having hydrogenated bisphenol group may have a chemical structure of wherein each of Ris independently H or methyl, and m and n are independently integers of 1 to 4. The bis-epoxy compound can be or a combination thereof, wherein each of Ris independently H or methyl, and each of Ris independently H or methyl.

Polymer and coating material

A method for forming an inorganic passivation material is provided. The method includes mixing about 5 to 80 parts by weight of trialkoxysilane, about 10 to 80 parts by weight of tetraalkoxysilane, and about 1 to 30 parts by weight of catalyst to perform a reaction at pH of about 0.05 to 4 to form an inorganic resin material. The inorganic resin material is modified by phosphate ester to form an inorganic passivation material, wherein phosphate ester is about 0.1-10 parts by weight based on 100 parts by weight of the inorganic resin material. An inorganic passivation material and a passivation protective film produced therefrom are also provided.
