Tetraethoxysilane : Guide
Tetraethoxysilane (Tetraethyl Orthosilicate) is a versatile compound widely used in the production of chemical-resistant coatings, heat-resistant coatings, silicone solvents, and precision casting binders. Through complete hydrolysis, Tetraethoxysilane generates fine silica powder, which can be used to create SiO2 and multi-component oxides using CVD and Sol-Gel methods.
This compound plays a key role in synthesizing silicone intermediates, refractory adhesives, and precision castings. It is also used as a cross-linking agent for room-temperature vulcanized silicone rubber. Additionally, Tetraethoxysilane is essential in the development of chemical-resistant and heat-resistant coatings, while its hydrolyzed form can be utilized in the production of phosphors, making it a critical material in various industrial applications.
