Product Code：SP201E
Product Name：Phenyltriethoxysilane
Product Introduction：
This product is prepared via alcoholysis. Raw materials fully react under catalytic conditions, followed by deep purification through vacuum rectification to effectively separate impurities. The finished product features stable purity and consistent batch quality. It is a colorless transparent liquid with mild and controllable hydrolysis and excellent storage stability. Its molecules contain phenyl and triethoxy functional groups, delivering outstanding heat resistance, anti-yellowing property, weather resistance and anti-corrosion performance, as well as good interfacial adhesion and insulation properties. As a mainstream organosilicon intermediate, it is widely used to synthesize phenyl silicone resins, modified silicone oils and specialty silicone rubbers. It also works as a coupling agent for filler modification, and finds extensive applications in weather-resistant coatings, electronic encapsulation and polymer composite materials.
