This chemical is primarily used as a coupling agent in the field of polymer chemistry, particularly in the modification of surfaces and interfaces. It plays a crucial role in enhancing the adhesion between organic polymers and inorganic materials, such as glass, metals, and ceramics. Its silane group allows it to bond effectively with inorganic substrates, while the caprolactam moiety facilitates compatibility with organic polymers. This makes it highly valuable in the production of composite materials, coatings, and adhesives, where improved interfacial strength and durability are required. Additionally, it is utilized in the development of advanced materials for automotive, aerospace, and construction industries, where performance under demanding conditions is essential.
