Product Name:Ethyl silicate
English Name:Ethyl silicate
CAS No.:78-10-4
Aliases:Tetraethyl orthosilicate, Tetraethoxysilane, Tetraethyl silicate, TEOS
Molecular Formula:C8H20O4Si
Physical Properties:Colorless transparent liquid with a characteristic odor. Density approx. 0.933 g/cm³, boiling point 168°C, flash point 46°C.
