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
