Product Code：SP202
Product Name：Diphenyldimethoxysilane
Product Introduction：
This product is synthesized via alcoholysis reaction. The reaction mixture is further purified by vacuum distillation to remove impurities and by-products, delivering finished products with high purity and consistent batch quality. It is a colorless transparent liquid with moderate chemical activity and mild, easily controllable hydrolysis reaction.
Its molecular structure contains diphenyl and dimethoxy groups, endowing the product with excellent heat resistance, yellowing resistance, weatherability and anti-aging properties. It forms dense films and features superior electrical insulation.
As a key organosilicon intermediate, it can be used for the synthesis of phenyl silicone resins, modified silicone oils and high-temperature resistant silicone rubbers. It is also applicable to anti-corrosion and weather-resistant coatings, electronic insulating encapsulating materials, inorganic filler modification and stone protection treatment. It is widely used in fine chemicals, electronic and electrical appliances, composite materials and other industries.
