Product Description:
Tetraethyl orthosilicate is widely used as a precursor in the production of silica-based materials, particularly in the synthesis of silica gels and coatings. It serves as a key component in the sol-gel process, where it undergoes hydrolysis and condensation to form thin films or nanoparticles. These materials are applied in anti-reflective coatings for optical lenses, protective layers for electronic devices, and as binders in refractory materials. It is also utilized in the manufacturing of adhesives and sealants due to its ability to enhance durability and resistance to environmental factors. Additionally, it plays a role in the creation of catalysts and as a crosslinking agent in polymers, improving their thermal and mechanical properties. In the field of nanotechnology, it is employed to fabricate nanostructured materials with tailored properties for advanced applications.
