Tetramethyl Orthosilicate (TMOS), also widely known as Tetramethoxysilane or Methyl Silicate, stands as a cornerstone chemical compound in numerous industrial applications. Produced by NINGBO INNO PHARMCHEM CO.,LTD., this colorless transparent liquid (CAS No. 681-84-5) is highly valued for its unique chemical properties and reactivity, making it an indispensable component across various sectors.

With a molecular formula of C4H12O4Si and a molecular weight of 152.22, Tetramethyl Orthosilicate exhibits specific physical and chemical characteristics that underscore its versatility. It has a density of approximately 1.023 g/mL at 25 °C and a boiling point ranging from 121-122 °C. Its melting point is around -4 °C, while its flash point is 26-28.9 °C, indicating its flammable nature under certain conditions. A critical property of TMOS is its hydrolysis in the presence of water or moisture, leading to the formation of silicon dioxide (silica) and methanol. This controlled hydrolysis is fundamental to many of its industrial uses, particularly in sol-gel processes where it can cure significantly faster than alternative systems like colloidal silica.

NINGBO INNO PHARMCHEM CO.,LTD. ensures that its Tetramethyl Orthosilicate meets stringent quality standards, typically boasting a purity of ≥99.0%. This high level of purity is crucial for its performance in sensitive applications.

The applications of Tetramethyl Orthosilicate are remarkably diverse, leveraging its ability to form stable silica structures or act as a reactive intermediate. One of its primary uses is as an inorganic binder for refractory fillers and pigments. This is particularly vital in fields such as precision investment castings, where it contributes to the strength and integrity of molds. Its rapid curing property also makes it an excellent choice as a second backup casting coating, offering efficiency and improved production cycles.

Furthermore, TMOS is a key component in advanced coating technologies. It is effectively employed as a binder in zinc-rich (corrosion-resistant) coatings, providing enhanced durability and protection against environmental degradation. Beyond coatings, Tetramethyl Orthosilicate serves as a fundamental starting material for the sol-gel process, enabling the synthesis of various silicate materials, including advanced ceramics and hexagonal mesoporous silica layers for catalysts. It also functions as a highly effective crosslinking agent for silicone sealants, contributing to their robustness and longevity, and as a drying agent in intricate sealing compositions. Its role as a crucial chemical intermediate further extends its utility in synthesizing other specialized compounds.
