Tetrapropoxysilane (TPOS), identified by CAS number 682-01-9, is a vital organosilicon compound widely utilized as a silane coupling agent and chemical intermediate. Its chemical structure, featuring a silicon atom bonded to four propoxy groups, grants it unique properties that are beneficial across numerous industrial applications. As a leading chemical supplier, understanding and providing high-quality TPOS is central to our mission of supporting innovation in materials science and manufacturing.

Chemically, Tetrapropoxysilane is a colorless transparent liquid with a molecular formula of C12H28O4Si and a molecular weight of approximately 264.44 g/mol. Its purity typically reaches ≥98.0% (GC), ensuring consistent performance in demanding applications. A key characteristic of TPOS is its controlled hydrolysis rate, which is slower than that of tetraethoxysilane. This property allows for extended pot life and greater control during processing, making it particularly suitable for applications where precise reaction kinetics are required, such as in the formulation of coatings, adhesives, and silicone rubber.

The applications of Tetrapropoxysilane are diverse and impactful. In the realm of coatings and paints, it serves as an adhesion promoter, enhancing the bond between organic binders and inorganic pigments or substrates. This leads to improved film integrity, durability, and resistance to environmental factors. For silicone rubber manufacturers, TPOS acts as a highly effective cross-linking agent. It facilitates the formation of a robust siloxane network, imparting excellent mechanical properties, high-temperature resistance, and flexibility to the final silicone products.

Furthermore, Tetrapropoxysilane is a crucial starting material in sol-gel processes. Through controlled hydrolysis and condensation, it can be converted into silica (silicon dioxide) networks, enabling the fabrication of advanced materials such as aerogels, silica nanoparticles, and protective films. These materials find critical use in areas like catalysis, electronics, and advanced ceramics.
