Used as a coupling agent in composite materials to improve adhesion between organic polymers and inorganic surfaces, particularly in glass fiber-reinforced plastics. Enhances durability and moisture resistance in coatings, sealants, and adhesives by promoting strong interfacial bonding. Commonly applied in the production of silicone-based hybrid materials and surface modifications where bromine functionality allows for further chemical derivatization. Also utilized in the synthesis of specialty silanes for use in electronics and nanotechnology due to its reactive alkyl bromide group.
