G-570, also known as 3-Glycidoxypropyltrimethoxysilane, is a silane coupling agent widely used in the composite materials, adhesive, and coating industries. Its molecular structure contains glycidoxy and trimethoxysilane groups, making it an effective adhesion promoter and surface modifier. In composite materials, G-570 promotes strong interfacial adhesion between inorganic fillers and polymer matrices, leading to composites with improved mechanical strength, thermal stability, and resistance to environmental degradation. Additionally, it is utilized in adhesives to enhance bonding between substrates, providing excellent moisture resistance and durability. In coatings, G-570 improves adhesion and durability on various surfaces, making it essential for protective coatings used in architectural and industrial applications.
