TEOS a Crosslinking Agent Tetraethylorthosilicate in Silicone Polymers

Synonym name:Ethyl silicate; Tetraethoxysilane; TEOS

Tetraethyl orthosilicate, formally named tetraethoxysilane and abbreviated TEOS

TEOS is mainly used as a crosslinking agent in silicone polymers and as a precursor to silicon dioxide in the semiconductor industry. TEOS is also used as the silica source for synthesis of some zeolites. Other applications include coatings for carpets and other objects. TEOS is used in the production of aerogel. These applications exploit the reactivity of the Si-OR bonds. TEOS has historically been used as an additive to alcohol based rocket fuels to decrease the heat flux to the chamber wall of regeneratively cooled engines by over 50%
