3-(2,3-Glycidoxy)propyltriethoxysilane: An Overview of its Properties and Applications
3-(2,3-Glycidoxy)propyltriethoxysilane is a versatile organosilane that is widely used in various industrial applications. It is commonly known as a coupling agent or adhesion promoter due to its ability to enhance the bonding strength between different materials. This article provides an overview of the properties and applications of 3-(2,3-Glycidoxy)propyltriethoxysilane, with a focus on its use in different industries.
Properties of 3-(2,3-Glycidoxy)propyltriethoxysilane
3-(2,3-Glycidoxy)propyltriethoxysilane is a clear, colorless to light yellow liquid with a molecular weight of 296.42 g/mol. It has a boiling point of 216°C and a flash point of 97°C. The chemical formula of this compound is C12H26O5Si, and its CAS number is 2602-34-8.
The key property of 3-(2,3-Glycidoxy)propyltriethoxysilane that makes it a useful coupling agent is its ability to form covalent bonds with both organic and inorganic surfaces. This is due to the presence of a reactive glycidyl group (-CH2-CH(OH)-CH2O-) and a triethoxysilane group (-Si(OC2H5)3) in its chemical structure. The glycidyl group can react with hydroxyl, amine, or carboxyl groups on the surface of the substrate, while the triethoxysilane group can hydrolyze and condense with other silane molecules to form a stable siloxane network.
