According to the news from Finance.com on June 2, 2025, information from the National Intellectual Property Administration shows that Guangdong Zhenchengda New Materials Co., Ltd. has applied for a patent entitled "A High - Refractive - Index Transparent Photo - Curing Mercapto Arylsiloxane and Its Preparation and Application", with the publication number CN120059192A and the application date of March 2025.
The patent abstract indicates that the invention belongs to the technical field of silicone materials, and specifically relates to a high - refractive - index transparent photo - curing mercapto aryl silicone oil and its preparation and application. The high - refractive - index transparent photo - curing mercapto aryl silicone oil is prepared by a hydrolysis polycondensation method. It contains aryl groups and photo - curable mercapto groups, which can achieve the characteristics of high refractive index, high light transmittance, good stability, etc. Meanwhile, it can be rapidly cured by thiol - ene photopolymerization under ultraviolet light. After curing, it has suitable mechanical strength and a transparent appearance. It can be applied in fields such as aerospace, electronic appliances, and high - temperature sealing that need to withstand high temperatures or have strict requirements on environmental pollution. Especially, it has a broad application prospect in fields such as optical materials, optoelectronic devices, and 3D printing, showing remarkable advantages and market potential.
