Tetraethyl orthosilicate, also known as tetraethoxysilane (TEOS), is an organic compound denoted by the formula Si(OC2H5)4. This colorless liquid undergoes degradation when exposed to water. TEOS serves as the ethyl ester of orthosilicic acid, Si(OH)4, and is widely recognized as the predominant silicon alkoxide.
Crosile® SI28 is a monomeric ethyl silicate, also known as tetraethyl orthosilicate (TEOS). After hydrolysis, it yields 28 wt.% silica, hence the name Ethyl Silicate-28. It has the following chemical formula.
Ethyl silicate Crosile® SI40 is an organic silicon compound with good solubility, stability and weather resistance, which is widely used in building materials, coatings, paints, cosmetics, electronic materials, plastics and other fields.
