Ethyl silicate consists of four ethyl groups attached to SiO44- ion, which is called orthosilicate. As an ion in solution, orthosilicate does not exist. Alternatively ethyl silicate can be considered to be the ethyl ester of orthosilicic acid. It is a prototypical alkoxide. It is mainly used as a crosslinking agent in silicone polymers and as a precursor to silicon dioxide in the semiconductor industry. Other applications include coatings for carpets and other objects. It is used in the production of aerogel. These applications exploit the reactivity of the Si-OR bonds.A liquid silicate that hydrolyzes to form a colorless, transparent film of Silica. For application, ethyl silicate is dissolved in an anhydrous ethanol solution. Small amounts of water will cause the solution to gel. Once applied, moisture from the atmosphere initiates irreversible hydrolyzation producing a solid silica film in less than an hour. Ethyl silicate was introduced as a paint vehicle in England in 1931 for painting outdoor murals. It is used with Alkali and Acid resistant Fresco pigments. The silicate colors are durable and resistant to weathering. More recently, ethyl silicate has been used for consolidating, strengthening and weatherproofing Stone, mortars, and cements.
