3-(2,3-glycidoxy)propyltriethoxysilane: A Revolutionary Silane Coupling Agent

Silane coupling agents play a vital role in numerous industrial applications such as adhesives, coatings, and composites. They are used to enhance the bonding strength between dissimilar materials by forming a covalent bond at the interface. Among the different silane coupling agents available in the market, 3-(2,3-glycidoxy)propyltriethoxysilane stands out due to its unique properties and versatile applications.

Also known as Glycidyl 3-Triethoxysilylpropyl Ether, 3-(2,3-glycidoxy)propyltriethoxysilane is a colorless liquid with a molecular weight of 298.43 g/mol. It contains a triethoxysilane group that enables it to bond with inorganic surfaces and a glycidoxypropyl group that can react with organic materials. This dual functionality makes it an ideal silane coupling agent for a wide range of applications.

Manufactured and supplied by INNO Specialty Chemicals from China, 3-(2,3-glycidoxy)propyltriethoxysilane is also available under different brand names such as DOWSIL Z-6042, Shin-Etsu Japan KBE-402, Momentive Silquest WetLink 78, CoatOSil 2287, and ShinEtsu KBE-402. Regardless of the brand name, the product's chemical composition and properties remain the same.

One of the primary applications of 3-(2,3-glycidoxy)propyltriethoxysilane is in the production of epoxy-based adhesives and coatings.
