Tetrabutyl orthosilicate is widely used as a precursor in the synthesis of silica-based materials. It is commonly employed in the production of coatings, adhesives, and sealants, where it acts as a cross-linking agent to enhance durability and resistance to environmental factors. In the electronics industry, it is utilized in the fabrication of thin films and insulating layers for semiconductors and optical devices. Additionally, it serves as a key component in sol-gel processes to create ceramics and glass materials with tailored properties. Its application extends to the field of catalysis, where it is used to prepare silica-supported catalysts for various chemical reactions. In the construction sector, it is added to concrete and cement formulations to improve strength and reduce permeability. Furthermore, it is employed in the manufacturing of specialty coatings for automotive and aerospace industries to provide corrosion resistance and thermal stability.
