Tetraisopropyl orthosilicate, also known as tetrakis(1-methylethyl)silicate, tetra(isopropyl)silicate, or tetraisopropoxysilane, is a versatile SiO2 precursor used in various industries. It is produced by Ningbo Inno Pharmchem Co., Ltd, a leading manufacturer and supplier of high-quality chemicals.
This article aims to promote the diverse applications of TIPS and highlight its benefits for manufacturers. We will discuss its properties, applications, and advantages over other SiO2 precursors.
Properties of TIPS
TIPS is a clear, colorless liquid with a pungent odor. It has a molecular weight of 208.33 g/mol and a boiling point of 221 °C. Its chemical formula is Si[OCH(CH3)2]4, and it is soluble in most organic solvents.
TIPS is a highly reactive compound that hydrolyzes rapidly in the presence of water to form silica gel and isopropanol. This property makes it an ideal precursor for the synthesis of silica-based materials, such as nanoparticles, thin films, and aerogels.
Applications of TIPS
TIPS has a wide range of applications in various industries, including electronics, coatings, adhesives, and textiles.
In electronics, TIPS is used as a precursor for the deposition of silicon dioxide (SiO2) thin films by chemical vapor deposition (CVD) or plasma-enhanced CVD (PECVD). These films are essential for the fabrication of microelectronic devices, such as integrated circuits and sensors.
In coatings and adhesives, TIPS is used as a crosslinking agent for polyurethanes, epoxies, and acrylics. It improves the mechanical, thermal, and chemical resistance properties of these materials, making them suitable for harsh environments.
In textiles, TIPS is used as a hydrophobic agent to impart water-repellent properties to fabrics. It forms a thin layer of silica nanoparticles on the surface of the fibers, which prevents water from penetrating the fabric.
Advantages of TIPS over other SiO2 precursors
TIPS has several advantages over other SiO2 precursors, such as tetramethyl orthosilicate (TMOS) and tetraethyl orthosilicate (TEOS).
First, TIPS is less toxic and less volatile than TMOS and TEOS. This property makes it safer to handle and transport, reducing the risk of exposure to hazardous chemicals.
Second, TIPS has a higher reactivity than TMOS and TEOS, allowing for faster hydrolysis and condensation reactions. This property makes it more suitable for high-throughput applications, such as the production of nanoparticles and thin films.
Third, TIPS has a lower viscosity than TMOS and TEOS, making it easier to handle and mix with other chemicals. This property also allows for better penetration into porous materials, such as fabrics and membranes.
Finally, TIPS has a lower cost than TMOS and TEOS, making it a more economical choice for large-scale production.
Conclusion
Tetraisopropyl orthosilicate is a versatile SiO2 precursor with a wide range of applications in various industries. Its properties, such as high reactivity, low toxicity, and low viscosity, make it a superior choice compared to other SiO2 precursors, such as TMOS and TEOS.
