Used as a surface modifying agent to impart hydrophobic properties to various materials. It is commonly applied in the treatment of glass, silica, and other surfaces to create water-repellent coatings. In the manufacturing of chromatographic columns, it enhances the separation efficiency by modifying the stationary phase. Additionally, it is utilized in the production of water-resistant textiles and paper. The chemical also finds application in the synthesis of silicone-based polymers and as a coupling agent in composites to improve adhesion between organic and inorganic components.
