TETRAETHYLORTHOSILICATE Chemical compatibility with O-rings, rubbers, & plastics

Tetraethyl orthosilicate (TEOS), also known as tetraethoxysilane, is a colorless liquid with the chemical formula Si(OC2H5)4, used primarily as a precursor in the production of silica and silicon-based materials. It is employed in various industrial and chemical applications, including the manufacturing of coatings, adhesives, and ceramics. TEOS is also used in the synthesis of certain polymers and resins, as well as in the production of thin films and optical fibers. Proper handling and storage of TEOS are essential to prevent accidents and ensure safety, as it is flammable and can pose health risks if inhaled or ingested. Safety measures, including the use of appropriate protective equipment and adherence to handling protocols, are crucial when working with TEOS. Its effectiveness as a precursor and its unique properties make TEOS a valuable chemical in numerous industrial and chemical applications, contributing to the production of a wide range of silicon-based products.
