Used as a coupling agent in silicone-based formulations to improve adhesion between organic and inorganic materials, especially in coatings and sealants exposed to harsh environments. Its trifluoromethylphenyl group enhances hydrophobicity and chemical resistance, making it suitable for water-repellent treatments on glass, metal, and ceramic surfaces. Commonly applied in automotive, aerospace, and construction industries to improve durability and moisture resistance of protective layers. Also utilized in the synthesis of hybrid materials for specialty composites and functionalized surfaces in electronic devices.
