This chemical is primarily used as a surface modifier and coupling agent in various industrial applications. It is commonly employed to enhance the adhesion between organic polymers and inorganic materials, such as glass, metals, or ceramics. In the production of composites, it acts as a bonding agent to improve the mechanical properties and durability of the final product. Additionally, it is utilized in the coating industry to create water-repellent surfaces or to improve the compatibility of coatings with substrates. Its ability to form stable bonds with surfaces makes it valuable in the manufacturing of adhesives, sealants, and protective coatings. In research, it serves as a reagent for introducing phenylpropyl groups into molecules during chemical synthesis.
