Used as a surface modifier in the production of silica-based materials, enhancing compatibility between organic and inorganic phases in composites. Commonly applied in the synthesis of hybrid polymers, where it improves adhesion, thermal stability, and mechanical strength. Frequently employed in coatings, sealants, and adhesives to promote water repellency and durability. Also utilized as a coupling agent in glass fiber treatments and in the manufacturing of specialty silicones for electronics and automotive industries.
