(3-Glycidoxypropyl)trimethoxysilane（Cat No.:L011101）is an organosilane compound with the molecular formula C9H20O5Si. It features a reactive epoxy group (glycidoxy) linked via a propyl chain to a silicon atom bearing three methoxy groups. This dual reactivity allows it to act as a coupling agent, adhesion promoter, and surface modifier in various materials. The methoxy groups hydrolyze to form silanols, which bond with inorganic surfaces, while the epoxy ring reacts with organic polymers. Commonly used in coatings, sealants, adhesives, and composite materials, it enhances durability, adhesion, and chemical resistance. It is a clear, colorless liquid requiring moisture-controlled storage.
