Tetraisopropyl orthosilicate (Cat No.:M121854) is a colorless liquid used primarily as a precursor in the synthesis of silica and silicon-based materials. It is composed of four isopropyl groups attached to a central silicon atom, and it readily reacts with water to form silica particles. TIOS is commonly employed in the production of silicone resins, sealants, and coatings, where it serves as a crosslinking agent to enhance material properties such as hardness, adhesion, and thermal stability. Additionally, TIOS is used in the manufacture of specialty glasses, and ceramics, and as a catalyst in organic synthesis.
