GENIOSIL TE 28

GENIOSIL TE 28 is monomeric ethyl silicate, also known as tetraethoxysilane or tetraethyl orthosilicate. It is a colorless low-viscous liquid with an SiO2-content of app. 28 wt.%.GENIOSIL TE 28 is being used for the precipitation of silica (polymeric SiO2 structures) by complete hydrolysis or thermal decomposition. Ethanol is generated as by-product.The polymeric SiO2 structures firmly bind inorganic fillers and pigments and adhere well to different inorganic substrates like glass, ceramics or metal. Typical applications• binder for refractory fillers (production of ceramic shells and cores)• precision casting• silica coating on pigments, fibers and other surfaces• source of finely divided silica• crosslinking agent, e. g. for silicone elastomers• water scavenger in sealants• sol-gel processes
