Used as a surface modifier in coatings and sealants to improve water and oil repellency. Enhances durability and stain resistance on textiles, glass, and construction materials. Provides low surface energy, making it effective in anti-fouling and release coatings. Commonly applied in architectural coatings, automotive finishes, and electronic protective layers where long-term environmental resistance is required. Also utilized in formulations requiring compatibility with both organic and inorganic matrices due to its silane functionality.
