Embodiment 1
[0069]KBM-403 (Shin-Etsu Chemical Co., Ltd.), TEMS (Sigma-Aldrich Corporation) and distilled water were mixed in a ratio of 414g: 134g: 67g (1.75mol: 0.75mol: 3.75mol), and the resulting mixture was added to In a 1,000mL double-jacketed reactor, add sodium hydroxide solution (0.1g of NaOH in 1g of H 2 O) as the catalyst, and the mixture was stirred at 90 °C with a mechanical stirrer at 200 RPM for 8 hours using a thermostat. Then, the resulting mixture was diluted with 2-butanone so that the solid content was 50% by weight, and then filtered through a 0.45 μm polytetrafluoroethylene filter to obtain a silicone resin. The molecular weight of the resin was measured by GPC, and the results showed that the number average molecular weight of the resin was 4,527, the weight average molecular weight was 6,280, and the polydispersity index (PDI, Mw / Mn) was 1.38.

[0073] KBM-403 (Shin-Etsu Chemical Co., Ltd.), DMDMS (Sigma-Aldrich Corporation) and distilled water were mixed in a ratio of 414 g: 90 g: 60 g (1.75 mol: 0.75 mol: 3.375 mol), and the resulting mixture was added to In a 1,000mL double-jacketed reactor, add sodium hydroxide solution (0.1g of NaOH in 1g of H 2 O) as the catalyst, and the mixture was stirred at 90 °C with a mechanical stirrer at 200 RPM for 8 hours using a thermostat. Then, the resulting mixture was diluted with 2-butanone so that the solid content was 50% by weight, and then filtered through a 0.45 μm polytetrafluoroethylene filter to obtain a silicone resin. The molecular weight of the resin was measured by GPC, and the results showed that the number average molecular weight of the resin was 3,216, the weight average molecular weight was 5,325, and the polydispersity index (PDI, Mw / Mn) was 1.65. Next, a resin composition for coating was prepared in the same manner as in Example 1, and was used to coat a polyi...

[0075] KBM-403 (Shin-Etsu Chemical Co., Ltd.), TEMS (Sigma-Aldrich Corporation) and distilled water were mixed in a ratio of 537g: 41.4g: 67.5g (2.27mol: 0.23mol: 3.75mol), and the resulting mixture Into a 1,000mL double-jacketed reactor, add sodium hydroxide solution (0.1g of NaOH in 1g of H 2 O) as the catalyst, and the mixture was stirred at 90 °C with a mechanical stirrer at 200 RPM for 8 hours using a thermostat. Then, the resulting mixture was diluted with 2-butanone so that the solid content was 50% by weight, and then filtered through a 0.45 μm polytetrafluoroethylene filter to obtain a silicone resin. The molecular weight of the resin was measured by GPC, and the results showed that the number average molecular weight of the resin was 5,897, the weight average molecular weight was 8,721, and the polydispersity index (PDI, Mw / Mn) was 1.47. Next, a resin composition for coating was prepared in the same manner as in Example 1, and was used to coat a polyimide film to pr...
