Applications
Uses1,2-Bis(triethoxysilyl)ethane is used as coating auxiliary agents, leather auxiliary agents, plastic auxiliary agents, surfactants and textile auxiliary agents. It is used to prepare mesoporous organosilica materials.
Uses1,2-bis(triethoxysilyl)ethane may be used to prepare mesoporous organosilica materials. Amine functionalization of mesoporous silica can be undertaken by this silane. It may form inorganic hybrid membranes with poly(vinyl alcohol). Effect of this crosslinking silane on the bonding of bis-GMA (bis-phenol-A-diglycidyldimethacrylate) resin to silicatized titanium was investigated.
General Description1,2-bis(triethoxysilyl)ethane is a non-functional silane and a double trialkoxysilyl precursor.
