摘要： A process is provided for producing curable polyorganosiloxanes where noble metal oxides are used as hydrosilylation catalysts. The noble metals can be used in solid granular form or as part of a fixed bed, and do not form part of the final curable composition or cured product. The cured polyorganosiloxanes have increased stability and can be used as encapsulation resins at a temperature far lower than 300° C., have excellent light transmission properties (colorless transparency) in a wavelength region of from ultraviolet light to visible light, light resistance, heat resistance, resistance to moist heat and UV resistance, and do not generate cracks and peeling even in use over a long period of time.
摘要翻译： 提供了一种制备可固化聚有机硅氧烷的方法，其中使用贵金属氧化物作为氢化硅烷化催化剂。 贵金属可以以固体颗粒形式或作为固定床的一部分使用，并且不形成最终可固化组合物或固化产物的一部分。 固化的聚有机硅氧烷具有增加的稳定性，并且可以在远低于300℃的温度下用作密封树脂，在从紫外光到可见光的波长区域具有优异的透光性（无色透明度），耐光性，耐热性 耐潮湿和耐紫外线，并且长时间使用时不会产生裂纹和剥离。

摘要： Curable polyorganosiloxanes are provided that cure in the absence of a hydrosilylation catalyst. The cured polyorganosiloxanes have increased stability and can be used as encapsulation resin is at a temperature far lower than 300° C., have excellent light transmission properties (colorless transparency) in a wavelength region of from ultraviolet light to visible light, light resistance, heat resistance, resistance to moist heat and UV resistance, and do not generate cracks and peeling even in use over a long period of time.
