Uses & manufacturing
General Manufacturing InformationSilicic acid (H4SiO4), tetrakis(2-butoxyethyl) ester: ACTIVE
Applications
UsesSilicon esters are silicon compounds that contain an oxygen bridge from silicon to an organic group, for example, Si-OR. Tetrakis(butoxyethoxy)silane can be used to modify suface of silica to obtain hydrophobic property, also being as crosslinkers for room temperature vulcanizing silicone sealant.
