Product Code:SP204E
Product Name:Methylphenyldiethoxysilane
Product Introduction:
This product is synthesized from methylphenyldichlorosilane and ethanol via catalytic alcoholysis. The reactants are refined by vacuum rectification to eliminate by-products and impurities, yielding finished products with stable purity and consistent batch quality.
It is a colorless transparent liquid at room temperature, featuring mild and easy-to-control hydrolysis reaction and excellent storage stability. Its molecular structure contains both methyl and phenyl groups, which endow the material with good flexibility, heat resistance and yellowing resistance, as well as superior weather resistance and anti-corrosion performance. It also has good compatibility with various resins and fillers.
As an important organosilicon intermediate, it is used for synthesizing modified phenyl silicone resins and special silicone oils, and for performance modification of silicone rubbers. It is also applied in weather-resistant coatings, electronic insulating encapsulation and inorganic filler modification. It is widely adopted in fine chemicals and new electrical materials industries.
