Used as a coupling agent in surface modification processes, particularly for enhancing the adhesion between organic polymers and inorganic materials. It is applied in coatings, adhesives, and sealants to improve durability and performance. Additionally, it is utilized in the production of functionalized surfaces for biomedical applications, such as biosensors or drug delivery systems, where precise surface chemistry is critical. Its trichlorosilane group allows for strong bonding to substrates like glass, metals, or ceramics, while the acetoxyundecyl group provides compatibility with organic matrices.
