Phenyltris(trimethylsiloxy)silane

Description:
Phenyltris(trimethylsiloxy)silane, with the CAS number 2116-84-9, is an organosilicon compound characterized by its silane structure, which includes a phenyl group and three trimethylsiloxy groups attached to a silicon atom. This compound is typically a colorless to pale yellow liquid, exhibiting low viscosity and volatility. It is known for its excellent thermal stability and resistance to moisture, making it useful in various applications, including as a coupling agent, surface modifier, and in the formulation of silicone-based materials. The presence of the phenyl group imparts aromatic characteristics, enhancing its compatibility with organic materials. Additionally, the trimethylsiloxy groups contribute to its hydrophobic properties, which can improve the performance of coatings and sealants. Due to its unique structure, Phenyltris(trimethylsiloxy)silane can also facilitate the modification of surfaces to enhance adhesion and durability in composite materials. Safety data should be consulted for handling and exposure guidelines, as with all chemical substances.
